CHAPTER 13: HOW MAGIC WORKS
What Magic Is
The Known World does not agree on a definition of magic. The Order of Magnus treats it as a natural phenomenon subject to rational inquiry — a force with structure, rules, and reproducible outcomes, documented in grimoires and cross-referenced in taxonomies of effect. The Húldar of Alvengaard experience it as an extension of their connection to the living world, something felt before it is understood. The Vartran carries it in blood, an inheritance from the Eymanarynn who received it as a gift from Ilya before the Second Era.
What every tradition agrees on is that magic requires something from the person wielding it. Attention, preparation, faith, blood, a patron's ongoing investment, and years of study. The universe does not give it away for nothing.
What no tradition fully agrees on is what magic actually is — where it comes from, why it persists, and why it fluctuates. Practitioners who have worked long enough notice it: a spell that lands clean one week and runs sluggish the next, with no change in preparation, no change in components, no obvious cause. The Order of Magnus has been cataloguing these fluctuations for three centuries. The patterns are real — irregular, but patterns — correlating with nothing in the natural world the Order has so far identified. Not seasons, not celestial cycles, not proximity to the Dead Lands. The Hyerophancy's records go back four centuries further than the Order's and show the same thing. Neither institution has published a convincing explanation, because neither has one.
The deeper truth — which the Order of Magnus has been documenting for three centuries and the Hyerophancy has known longer — is that magic in the Known World runs through the same substrate as the Darkness ran through. The banishment sealed the Darkness out of the mortal plane, but it did not cleanse the channels it used. Every act of arcane magic touches those channels. Most of the time, this is inconsequential. In the Dead Lands, where the banishment was fought and won at tremendous cost, it is anything but.
The Three Sources
Magic in Sonata draws from three fundamentally different sources. Which source a spell draws from determines how it behaves, who can cast it, and what happens when something goes wrong.
Arcane magic draws from the raw structural forces underlying reality — the same forces the Darkness moved through, which is why the Church of Tar'amaan views arcane practice as contamination rather than skill. Mages, Sorcerers, and Bards access arcane magic. Mages learn to construct spells from scholarly first principles. Sorcerers receive them through a patron relationship that mediates access to those forces. Bards carry fragments of arcane tradition through oral transmission, understanding less of the theory but enough of the practice to produce real effects.
Divine magic channels power that flows from a deity or from the accumulated spiritual force of a religious tradition. Clerics access it through institutional membership in a faith — their deity's investment in the institution flows to them as individual members. Paladins access it through direct calling, which is why a Paladin's relationship with their deity is personal in a way a Cleric's frequently is not. Divine magic does not touch the same channels as arcane magic, does not trigger the resonance effects in contaminated areas to the same degree, and cannot be studied the way arcane magic can.
Primal magic channels the forces of the living world — the same forces that moved through natural systems before the Darkness interrupted them. Druids access it through the Hierophancy's investiture, which is not merely political but a genuine transfer of attunement. This is why the Compact means what it means: non-investitured practitioners are not just breaking a law, they are accessing forces they have not been attuned to correctly, producing results the Hyerophancy considers dangerous. Warden Rangers access a version of this through demonstrated connection and Druidic recognition — the full investiture withheld, but enough granted to work.
Memorization
Mages and Clerics prepare spells through memorization — a process of loading a specific magical formula into active mental readiness so it can be cast without the hours of preparation required to formulate it from scratch.
For Mages
Mages memorize spells from their grimoire during an uninterrupted rest period of at least eight hours. The total spells memorized per spell level cannot exceed the number listed in the Wizard Spell Progression table in Appendix A. A memorized spell is fully loaded into working memory — it can be cast in a round, at the cost of wiping it from memory once released. Re-memorizing requires another rest period and access to the grimoire.
A Mage who does not have access to their grimoire can memorize only spells they already had memorized from a previous rest period that have not yet been cast. No new spell levels can be prepared, and no used spells can be refreshed.
A Specialist Mage memorizes an additional spell per level in their school of specialization, beyond the standard progression.
For Sorcerers
Sorcerers do not use grimoires. Their spells are internalized through teaching and meditation, held in memory as known spells rather than formulas. The practical effect is similar — a Sorcerer who has cast a spell for the day has exhausted that slot and must rest to recover it — but the source differs. A Sorcerer who loses their patron does not lose spells already memorized and known. They simply cannot learn new ones.
For Clerics
Clerics receive their spells through prayer rather than study. The process is devotional: a Cleric who prays for one hour at a designated time (typically dawn, though specific faiths vary) requests spells from their deity through the institutional channel of their faith. The deity responds by investing those spells in the Cleric's memory. This is not automatic. A Cleric whose conduct has violated their deity's principles may find the prayer unproductive.
Clerics receive bonus spells from Wisdom beyond the standard progression. See Table 1.5.
Clerics do not maintain spell lists in the way Mages do — they request, and their deity provides within the Cleric's spell level capacity. This means Clerics have daily flexibility about which specific spells they prepare, while Mages are locked to what their grimoire contains.
For Druids
Druids memorize spells from the Priest list with emphasis on nature-affecting magic. Their memorization functions identically to Clerics — prayer to the invested channel of primal magic they access through the Hyerophancy. A Druid whose Hierophantic investiture has been revoked cannot memorize spells. The investiture is the connection; without it, the prayer has no channel to travel.
Casting
Casting a spell is a full mental commitment. A spellcaster who declares a spell is casting it — the process begins at that moment and cannot be changed until the spell resolves or the caster is interrupted.
Components
Arcane spells draw on three types of components: verbal (spoken formulations), somatic (precise hand movements), and material (physical substances). Each component type governs a distinct axis of the spell's effect. Losing a component reduces that axis — it does not cancel the spell.
Divine and primal spells use verbal and somatic components expressed as prayers, gestures, and ritual actions specific to the faith or tradition. The same restrictions apply: a Cleric cannot cast a spell with vocal components while silenced, any more than a Mage can.
Verbal (V) — Range: The spoken incantation carries the spell outward. Without it — casting in silence, or whispering when the formula requires full voice — the spell's range is halved. For touch spells and self-only effects where range is not the relevant axis, the penalty falls on duration instead: halved, rounded up.
Somatic (S) — Area: The gesture shapes the effect. With restricted hands — grappled, armored, or deliberately restrained — the area of effect is halved. For single-target spells with no area, the penalty applies to the target's saving throw instead: the target rolls with a +4 bonus to resist.
Material (M) — Potency: The physical substance anchors the power. Without it, damage, healing, and effect magnitude are halved, rounded up. For utility spells with no quantitative effect, the penalty falls on duration: halved, rounded up.
Component Penalty Summary
| Component Missing | Primary Penalty | Secondary (if primary inapplicable) |
|---|---|---|
| V | Range halved | Duration halved (rounded up) |
| S | Area halved | Target's saving throw +4 |
| M | Potency halved (rounded up) | Duration halved (rounded up) |
Multiple missing components stack. A spell cast without any components applies all three penalties simultaneously. It still functions — at significantly reduced capacity.
Mandatory Components
Some material components are not sympathetic anchors — they are narratively inseparable from the spell's mechanism. A speak with dead that requires material from the corpse. A gate that requires material from the destination. These are flagged [Mandatory] in the spell entry. No substitution is possible. If the component is unavailable, the spell cannot be cast.
Mandatory components are rare across the full spell list and are never Common tier. A component that is easy to acquire functions as an optional booster, not a structural gate.
Component Substitution
Components work through sympathetic resonance, not arcane chemistry. A pinch of sulfur does not contain fire magic — it corresponds to it. A Mage without the listed component can ask whether something on hand resonates similarly. The GM answers based on logic, not a lookup table. A torch might substitute for sulfur. A live coal might not. The fiction guides the ruling.
Component Availability
Components fall into four tiers that govern both GM preparation and player resource planning.
| Tier | Cost Range | Availability | Examples |
|---|---|---|---|
| Common | Free – 1 gp | Anywhere | Bat guano, sand, fleece, chalk, candle wax, common herbs |
| Uncommon | 5 – 50 gp | Any town with a functioning market | Powdered gemstones, rare herbs, preserved animal parts, alchemical basics |
| Rare | 100 – 500 gp | Cities and specialist vendors | Quality gems, dragon-adjacent materials, refined alchemical compounds |
| Exceptional | 1,000 gp+ | Quests, specific locations, unique sources | Singular or irreplaceable materials, often tied to specific narrative events |
Common components are assumed present unless the party has been stripped of gear, has been on the road for weeks without resupply, or the GM has a specific reason to rule otherwise. Do not ask players to track Common components. That accounting problem is what made components a nuisance in the source material; eliminate it at this tier.
Uncommon and above are worth tracking. These are the components a spellcaster packs deliberately before a known engagement, trades for in a city market, or loses when their pack is burned.
Enhancing Spells: Double-Cast and Potency Boost
A Mage or Bard who casts a spell using the appropriate sympathetic material component — at Common tier or above — may choose one of two enhancements at the moment of casting, before rolling. The choice is made before the spell resolves and cannot be changed.
Double-Cast. The memorized spell slot is not expended on the first casting. The caster may cast the same spell a second time before their next rest. The slot is expended normally on the second casting.
Potency Boost. The memorized slot is expended as normal, but the spell's effect is enhanced. The specific enhancement is defined per spell or school. The general principle: one die step up on damage, one category up on effect strength, or saving throw difficulty increased according to the caster's tier (see below).
The enhancement strength scales with the caster's level.
Boost Strength by Caster Tier
| Tier | Caster Levels | Spells Available | Potency Boost | Saving Throw Difficulty |
|---|---|---|---|---|
| I | 1–5 | Up to 3rd-level | One die step up | +2 |
| II | 6–10 | Up to 5th-level | One die step up, plus one additional die on single-die spells | +3 |
| III | 11+ | 6th-level and above | Maximum result on damage dice — no roll required | +4 |
Double-cast does not scale with tier. The extra casting is the benefit, regardless of level.
Restrictions
- Once per rest, per spell. A caster cannot double-cast the same spell twice in the same day, regardless of how many component pouches they carry.
- Daily cap by Intelligence score. The total number of enhancements a Mage or Bard can apply in a single day is determined by their Intelligence score. Both a Double-Cast and a Potency Boost count separately against this cap.
| Intelligence | Daily Enhancement Cap |
|---|---|
| Below 13 | 0 (not eligible) |
| 13–15 | 1 |
| 16 | 2 |
| 17 | 3 |
| 18–19 | 4 |
| 20 | 5 |
| 21 | 6 |
| 22 | 7 |
| 23 | 8 |
| 24 | 12 |
| 25 | 20 |
Intelligence above 25 is outside the scope of normal play; treat as 25.
Specialist Mages and Material Components
A Mage who specializes in a school of magic develops a degree of mastery over that school's principles sufficient to make the material component redundant — for spells from that school only. The Specialist has internalized the resonance the component would otherwise provide. The substance is no longer the anchor; they are.
The exemption applies only to spells from the chosen school. Spells from other schools still require material components as normal.
This is not a convenience, but what years of narrowed focus produce. The Specialist entry price is a steeper Intelligence requirement than the Generalist threshold; the M-component exemption is what that investment looks like at the table.
Sorcerers: HP Cost
Sorcerers carry their power in themselves. External materials are not the channel through which their magic moves, which means the enhancement mechanics work differently for them. When a Sorcerer wants to apply a Double-Cast or Potency Boost, they spend hit points rather than material components.
HP Cost for Potency Boost: Spell Level × 3
HP Cost for Double-Cast: Spell Level × 5
| Spell Level | Potency Boost Cost | Double-Cast Cost |
|---|---|---|
| 1st | 3 HP | 5 HP |
| 2nd | 6 HP | 10 HP |
| 3rd | 9 HP | 15 HP |
| 4th | 12 HP | 20 HP |
| 5th | 15 HP | 25 HP |
| 6th | 18 HP | 30 HP |
| 7th | 21 HP | 35 HP |
| 8th | 24 HP | 40 HP |
| 9th | 27 HP | 45 HP |
A Sorcerer may spend HP down to 0 — they fall unconscious immediately after the spell resolves. A Sorcerer cannot spend HP they do not have: a Sorcerer at 3 HP cannot double-cast a 2nd-level spell.
A Sorcerer stripped of everything — gear gone, dungeon walls closing in — can still burn. What they pay is what they have.
The daily cap follows the same table as Mages, but uses the Sorcerer's Wisdom score as the lookup value instead of Intelligence. This is consistent with the Sorcerer class, where Wisdom is the prime requisite and governs spell capacity. The once-per-rest-per-spell restriction applies identically. The cap is governed by Wisdom, not Charisma.
Bards and Components
Bards access spells through oral tradition and practical observation — retained in memory rather than written formula, learned by watching and listening rather than by studying the theoretical structures underlying the effect. This is observational knowledge, and observation alone does not produce the internalized resonant understanding that earns a Specialist their material component exemption.
Bards operate identically to Generalist Mages for component purposes: full V + S + M dependency, no exemptions on any axis. Enhancement follows the same rules — appropriate material component, same options, same daily cap by Intelligence score.
The three arcane traditions at a glance:
| Tradition | Component Dependency | Enhancement Method |
|---|---|---|
| Generalist Mage / Bard | Full V + S + M | Appropriate material component |
| Specialist Mage | V + S for chosen school; full dependency elsewhere | No material component required for the chosen school |
| Sorcerer | None required | HP expenditure (see table above) |
Casting Time
Most spells have a casting time expressed in segments — fractions of a round — or in rounds. A spell with a casting time of 1 segment resolves on the caster's initiative with a −1 modifier. A casting time of 5 reduces the caster's initiative by 5. Spells taking a full round or longer begin at the start of the round and resolve at the end or at a specified later point.
While casting, a Mage cannot move. A Cleric or Druid may move at one-quarter speed while casting certain prayers at the GM's discretion, but this is the exception.
Interruption
A spell in progress can be broken. If the caster takes damage, fails a saving throw, or is physically disrupted at any point before the spell resolves, concentration breaks. The spell fails. The slot is expended as though the spell had been cast — the mental loading unravels whether or not the effect occurs.
This is one of the most tactically important rules in the game. A Mage declaring a fireball is vulnerable from declaration to resolution. Opponents who understand this will prioritize disrupting the cast. Players who understand this will use the Wait action to interrupt before the caster's initiative is reached.
Spell Failure and Misfire
Beyond interruption, several conditions create a chance of spell failure regardless of whether casting completes.
Wisdom below 13 (Cleric/Druid). Priests with Wisdom in this range have a spell failure chance listed in Table 1.5. Roll percentile dice before the spell resolves; a result below the failure chance means the spell fails.
Armor (arcane casters). Mages and Sorcerers cannot cast arcane spells while wearing armor. The restriction is not about the physical range of motion — armor interferes with the fine somatic control that arcane formulas require. Leather armor is marginal; most arcane casters avoid it. Chain and above make casting impossible. This restriction does not apply to divine or primal magic.
Dead Lands resonance. See below.
Schools of Magic
All arcane spells belong to one of nine schools, which represent the theoretical categories the Order of Magnus uses to organize and transmit magical knowledge. The division is not merely academic — Specialist Mages choose one school as their primary focus and accept a corresponding restriction on their opposing school.
The schools and their oppositions are listed in Chapter 3 and in the Schools of Magic table in Appendix A. What that chapter does not fully articulate is the in-world meaning of each school:
Abjuration creates barriers, protections, and cancellations of effect. The Order considers it the most defensive school — useful, conservative, and frequently underestimated.
Alteration changes the properties of existing things. The school is most closely associated with practical applications: transformation, improvement, and modification of natural phenomena.
Conjuration/Summoning brings things from elsewhere — materials, creatures, extraplanar entities. The risks associated with this school are grounded. What you summon does not always leave when you are done with it.
Divination gathers information. The school the Chroniclers most actively study and that the Church of Tar'amaan most actively restricts, for reasons the Church makes explicit in their doctrine.
Enchantment/Charm affects minds. More than any other school, this one generates ethical arguments in every culture that has thought about it, which is all of them.
Illusion/Phantasm creates false perception. The school most associated with Messalya's aesthetic tradition of magic, where the refinement of illusory craft is considered an art form distinct from its combat applications.
Invocation/Evocation channels direct energy — fire, force, electricity. The simplest school to understand and the most immediately destructive. The one most heavily associated with the Order of Magnus's military history.
Necromancy manipulates life force, death energy, and the boundary between the two. Illegal in most of the Known World. Practiced in shadows in all of it. The resonance effects of the Dead Lands make necromantic spells particularly unpredictable in that region — the boundary they manipulate is already compromised there.
Greater Divination accesses knowledge from beyond normal information channels — true sight, reading the future, scrying. Distinct from standard Divination in the depth of access and the correspondingly higher risk of what is looking back.
Magic and Religion
The relationship between arcane magic and divine faith is not neutral in the Known World, and pretending otherwise is a failure to understand the political landscape characters will operate in.
The Church of Tar'amaan is an NPC faction — a supremacist order, hostile to arcane practitioners, and one of the primary antagonists of the Known World. Their position is that arcane magic is the mechanism by which the Darkness entered the mortal plane, and that its continued use reopens that wound. This is not a metaphor in Tar'amaan theology. The Church believes, and teaches, that every arcane spell cast increases the risk of another Darkness. Their Inquisition exists to reduce that risk by eliminating practitioners. That their theology is directly contradicted by what the Order of Magnus has documented about the Second Era — and disputed by every other religious tradition — does not reduce its political effectiveness in Cadmano-controlled territory. Player characters cannot be members of the Church of Tar'amaan.
The Ilianist position — the Old Faith of the Three Sisters — holds that Ilya gave magic to the Eymanarynn and to the Húldar freely and without condition. Magic is not inherently corrupting. Its effects depend on the intention and conduct of the practitioner, not the act of casting. This position does not protect practitioners in Cadmano territory, but it explains why the Old Faith and the Church are in active conflict everywhere Norderenn's occupation reaches.
The Faith of the Nine (Val'arian tradition) takes no institutional position on arcane magic and regards it with the same cultural curiosity it applies to everything it does not yet fully understand. Val'arian Sorcerers practicing within Bal'mekh's borders operate with more social latitude than they would anywhere near Cadmano influence.
Boroism (Urgônia and Gwan'tor) considers magical capability a skill like any other. A Sorcerer who cannot control their power is no different from a warrior who cannot control their weapon — technically capable, practically dangerous. The question is whether you have mastered what you carry.
Magic in the Dead Lands
The Dead Lands are where the final conflict of the Second Era was fought. The Darkness was banished there, at tremendous cost, and its absence did not leave the region clean. The channels through which it moved are still present, still open at the edges, and still reactive to magic in ways that normal terrain is not.
Casting any arcane spell in the Dead Lands requires an additional check. When the spell is declared, roll 1d6 alongside the normal casting procedure.
| Result | Effect |
|---|---|
| 1 | The spell functions, but leaves a mark. The GM advances one step on the Resonance track for this character. |
| 2–5 | The spell functions normally. |
| 6 | The spell functions, and the caster recovers one spent spell slot of the same level or lower. |
The Resonance track is a campaign-level pressure system, not a per-session mechanic. The GM maintains it in secret. When the track completes — the number of steps depending on the depth of Dead Lands territory and the GM's calibration — the caster experiences a Resonance effect. These are lasting changes to how the character interacts with magic: sensory distortions, involuntary manifestations, and alterations to spellcasting behavior. The GM designs these in keeping with the character's magical tradition and the nature of what they have been casting.
Resonance effects are evidence of what this place is and what the caster has been doing — not punishment. A character carrying a Resonance effect carries proof of having worked in the most dangerous arcane environment in the Known World, and that proof is visible.
Divine and primal magic are less susceptible to the Dead Lands' influence, though not immune. The channels through which divine magic travels do not overlap with the Darkness's pathways in the same way. Divine casters in the Dead Lands do not use the Resonance track. They do not, however, find the environment spiritually neutral — the volume of death, corruption, and residual necromantic energy produces a sustained pressure that most Clerics and Druids describe as exhausting rather than dangerous.
Spell Research
Characters who wish to learn spells not found in existing grimoires, develop variations on known spells, or create entirely new magical effects can conduct original research. The costs are real.
Requirements
Spell research requires a laboratory or equivalent workspace. Minimum investment: 1,000 gp per spell level in equipment and materials before any research begins. The workspace is consumed by the research; it can be reused for subsequent projects, but must be maintained.
Time
Research takes one week per spell level at a minimum, plus one week per unusual component or effect being incorporated. The character is not available for adventuring during active research weeks. A character interrupted mid-research can resume from where they left off; the materials consumed by the interrupted week are lost.
The Research Roll
At the end of the required weeks, the caster makes a percentile roll. Success chance: 15% + the caster's applicable attribute (Intelligence for Mages, Wisdom for Clerics and Druids) + 5% per level of experience above the minimum needed to cast the spell's level.
On success, the spell is developed and added to the grimoire (or the Cleric's known prayers, in the case of divine research). On failure, the research is lost and must restart from scratch.
Sorcerers and Research
Sorcerers cannot conduct formal spell research. Their magic comes through the patron relationship, not independent scholarship. A Sorcerer who wants access to a spell their patron has not taught them has one option: ask the patron. What the patron does with that request is entirely the patron's business.
Reversed Spells
Some spells have reversed versions — healing becomes harm, light becomes darkness. Any caster with access to the original spell can cast the reversed version without research. The reversed version uses the same slot and follows the same rules. A Cleric whose alignment or deity prohibits the reverse may not cast it.
Magical Items: Use and Crafting
The full catalogue of magical items appears in Book III. This section covers only the rules for using and creating them.
Using Magical Items
Most magical items can be used by any character who can physically employ them — anyone can drink a potion, anyone can carry a ring. Items restricted by class or ancestry, note this in their description.
Activating items. Some items activate by command word, worn contact, or proximity. Others require conscious activation — an act of will that in most cases counts as a standard action. Items that activate automatically (a ring of protection, for example) require no action and function continuously while worn.
Identifying items. A magical item found in the field is not automatically understood. Its properties must be discovered through use, research, or the Identify spell. Using an item before it is understood is possible; this is also how most characters learn what cursed items do.
Charges. Many items have limited charges. When charges are exhausted, the item loses its magical properties but retains its physical form. Some items can be recharged; most cannot. The item's description specifies.
Crafting Magical Items
Creating a magical item requires: the ability to cast all spells being placed into the item, the item itself in masterwork quality, a fixed investment of time and gold, and, in many cases, rare material components.
Time and cost. Baseline: one week and 1,000 gp per spell level of the item's most powerful enchantment. Multiple enchantments multiply this cost. These are irreducible minimums — they represent the actual physical and magical investment required. A character cutting costs gets a defective item.
Spell availability. Every effect in the item must be a spell the crafter can cast, or a permanent effect the crafter can produce. A Mage who wants to craft a holy avenger cannot, because the item's properties require divine magic that they cannot access.
Enchanting weapons and armor. Weapons and armor require metal of exceptional quality, as the base — standard smithing produces items that can hold one charge; masterwork quality allows permanent enchantment. The enchantment bonus cannot exceed the caster's ability to produce that level of magical effect through existing spells.
Scrolls. Mages can scribe any spell they know onto a scroll. Cost: 100 gp × spell level, plus one day per spell level of uninterrupted work. Sorcerers cannot scribe scrolls — the written formula is not the channel through which their magic moves. Clerics can scribe divine scrolls; Druids can scribe primal scrolls. No cross-tradition scribing is possible.
Potions. Any spellcaster with access to the relevant spell and at least 5th level can brew potions. Base cost: 200 gp per spell level. Brewing time: one week per potion, regardless of spell level.
Destroying magical items. Most items can be destroyed by sustained physical damage or specific magical effects. Artifacts — the most powerful items in the world — cannot be destroyed by normal means; the methods required are specific, dangerous, and usually the subject of a separate quest. An item reduced to 0 HP from a physical attack is physically destroyed. Whether the magical charge dissipates or persists in a dangerous form depends on what was stored in it.
Magical Item Malfunctions
Certain ancestries have a higher chance of magical item malfunction, detailed in Chapter 2. When a malfunction occurs, the item activates erratically — the effect fires at a random target, produces an unintended result, or the charge is consumed without effect. The character may try again on a subsequent activation attempt; repeated failures on the same item suggest fundamental incompatibility.
Open items flagged for design finalization:
Flag 1 — Potency boost definition per school. "One category up on effect strength" requires concrete language for non-damage spells across different schools. Enchantment/Charm and Illusion/Phantasm are the highest priority — their effects are qualitative rather than quantitative. A sidebar or table mapping school-specific boost effects will prevent table arguments.
Flag 2 — Scaling breakpoints. Boost tier breakpoints are derived from standard 2e spell level progression. Confirm against the final Chapter 13 spell progression table and Appendix A once available.
Flag 3 — GM improvisation guidance for component substitution. A short sidebar — principles for on-the-fly rulings, not an exhaustive list — should be written once the rules text is locked.
