CHAPTER 4: MULTICLASSING
A character's class represents the core of their training. Multiclassing represents what happens when that training expands — when a soldier discovers they have a gift for magic, when a thief finds themselves in service to something they are willing to die for, when a scholar realizes that the knowledge they want cannot be acquired from books alone.
Multiclassing is a single unified system. Dual-classing — the old practice of abandoning one class, enduring a period where neither class's abilities were fully available, and eventually regaining the original — is not used in Sonata. Every character who pursues a second class does so without losing anything they have already built.
How Multiclassing Works
Starting a Second Class
A character may begin multiclassing at any point in their career, including mid-campaign. When they do, their existing class becomes the Primary class. The new class becomes the Secondary class, starting at level 1.
No abilities are lost. Both classes are active from the moment multiclassing begins.
To take a secondary class, a character must have a score of 13 or higher in that class's core attribute. This requirement applies at the moment multiclassing begins and cannot be met retroactively.
Table 4.1: Core Attributes for Multiclass Entry
| Class | Core Attribute |
|---|---|
| Fighter, Ranger, Paladin, Champion | Strength |
| Mage | Intelligence |
| Sorcerer | Wisdom |
| Cleric, Druid | Wisdom |
| Thief, Bard | Dexterity |
All ancestry restrictions from Chapter 2 and class restrictions from Chapter 3 apply to secondary classes as well. A character cannot multiclass into a class unavailable to their ancestry, and racial level caps apply to each class individually within a multiclass configuration.
XP Distribution
Experience points are divided between classes at the end of each session. The Primary class receives two-thirds of all earned XP. The Secondary class receives one-third. No XP is lost — all of it is allocated.
| Configuration | Primary Class | Secondary Class |
|---|---|---|
| Standard (two classes) | 2/3 of XP | 1/3 of XP |
A character who begins multiclassing at a high level will find their secondary class advances in levels faster initially — the XP required for early levels is lower. Meanwhile, the primary class slows. This reflects a character whose new pursuit accelerates while their original path decelerates. It is a consequence of the XP split, not a flaw.
The Human Advantage: Primary Reassignment
Once per character lifetime, a human may swap which class is Primary and which is Secondary. This can be done at any level, at any time, with no penalty and no loss of abilities. The reassignment takes effect immediately. After the swap, XP is distributed according to the new designations.
Non-human characters cannot reassign. Their first class is always their Primary class for life.
This replaces the function of the old dual-classing system. A Fighter who has become primarily a Wizard — their combat past receding behind their arcane future — can formalize that shift through the reassignment. The character's history does not vanish; the weights simply change.
Attack Bonus
Use the highest Attack Bonus across all classes at their current levels. Do not add bonuses together.
Saving Throws
Use the best save score across all classes for each of the three saves individually. Fortitude, Reflex, and Will are each evaluated separately. A character uses the best Fortitude from any class, the best Reflex from any class, and the best Will from any class.
Hit Points
At each level gained in any class, roll that class's hit die and add the Constitution modifier once. Halve the total, rounding up. This applies every time a level is gained in either class.
Example: A Fighter (d10) / Wizard (d4) gains a Fighter level. Roll 1d10, add the Constitution modifier, divide by 2, round up. The Constitution modifier is added once per level gain, not once per class.
Weapons and Armor
A multiclass character may use any weapon or armor permitted by either class. Restrictions still govern the abilities of the class that imposed them. A Fighter/Mage can wear plate mail, but doing so prevents arcane spellcasting — the Mage's restriction on casting in armor is not lifted by the Fighter's proficiency. Each class's restrictions govern that class's abilities specifically.
Multiclassing as a Mage
A multiclassed Mage who chooses Specialization retains the M-component exemption for their school regardless of their secondary class. The exemption belongs to the Specialization, not to being a pure Mage.
Class Limit
A character may have one Primary class and one Secondary class. No further classes may be added unless the GM introduces the optional three-class rule below.
Optional Rule: Three-Class Multiclassing
Include only if the GM chooses to introduce this variant.
A character may multiclass into a third class, subject to the same entry requirement of 13 or higher in the new class's core attribute, all ancestry restrictions, and all racial level caps. When three classes are active, XP is distributed as follows:
| Configuration | Primary Class | Each Secondary Class |
|---|---|---|
| Three classes | 50% of XP | 25% of XP each |
The Human primary reassignment still applies to the Primary class only. The tertiary class always remains at 25% and cannot be promoted.
Three-class multiclassing is a significant sacrifice. Primary class advancement at 50% XP is slow past mid-levels. Players choosing this path are trading peak effectiveness for breadth. The GM should ensure players understand this before committing — it is a character concept decision, not a power choice.
Becoming a Sorcerer Mid-Campaign
A character who did not begin play as a Sorcerer may take levels in the class during a campaign, subject to the ancestry restrictions, ability score requirements, and multiclassing rules described above. The mechanical requirements are identical to any other class.
What is different is the fiction surrounding them.
A Sorcerer without a patron is not a Sorcerer. This means that before a single level can be taken, the character must find something willing to teach them — and persuade it that the arrangement is worth its time. That is not a skill check, but a campaign arc.
Finding a patron worth approaching requires knowledge the character probably does not have at the outset: what kinds of entities offer this kind of arrangement, where they can be reached, what they respond to, and what they have historically wanted in return. Acquiring that knowledge means talking to people who know, which means being known as someone looking — which means that certain parties will become aware of the character's intentions before the character is aware of those parties. Patrons do not always wait to be found.
The negotiation itself is the second problem. An entity capable of conveying arcane knowledge across the gap between its nature and a mortal's is not desperate for apprentices. It has terms. Those terms may be acceptable, or they may require the character to agree to something whose full implications will not be clear until later in the campaign. A patron who seems straightforward at the negotiating table has usually already decided what they intend to ask for.
The third problem is what the arrangement does to everyone else. A character who has secured a patron is now in a relationship with something that has its own interests and its own reach. That relationship does not stay neatly contained to the character who made it. Patrons notice the people around their Sorcerers. Sometimes they find them useful. Sometimes they find them inconvenient. The party should understand, before a character commits to this path, that they are consenting to share the consequences.
None of this is regulated by a rule. The GM sets the difficulty, determines what the patron wants, and decides when the negotiation has reached a conclusion that warrants granting the first level. That conclusion might come after a single focused session or after months of campaign time, depending on what the character pursued and what they were willing to accept.
The XP cost for the first Sorcerer level begins counting from the moment the patron agreement is finalized. Everything before that is the price of the agreement itself.
GMs should resist the temptation to resolve this arc quickly as a favor to an eager player. The pursuit of a patron is one of the most generative narrative structures available in a campaign — it creates factions, debts, and hooks that will pay dividends long after the character has their first spell. Rushing through it wastes the best part.
The Weight of Certain Combinations
Most multiclass combinations are professionally legible — a Fighter who learns to pick locks, a Ranger who studies divine scripture. The Known World accommodates them without comment. The combinations below are different. Each one sits at the intersection of two institutional worlds or two ethical frameworks that the Known World has a specific opinion about, and playing them means navigating that opinion.
These entries are not warnings. They are the part of the character concept that generates play.
Cleric/Thief
Every major faith in the Known World has a theological position on theft. Most of them are negative. A Cleric/Thief is someone who has found a way to inhabit both sides of that position simultaneously — either through genuine personal reconciliation, or through careful institutional concealment.
The reconciliation path produces characters of genuine philosophical interest: what does it mean to steal in service of a deity whose doctrine condemns it? What exceptions has the character constructed, and how sturdy are they under pressure? Some faiths are more pragmatic than others about operatives who can go where priests cannot, and a Cleric/Thief in service to a deity of knowledge or secrets may face less internal friction than one serving a god of law and order.
The concealment path is simpler and more dangerous. The Church of Tar'amaan considers this combination grounds for investigation if discovered — not because the theology is particularly clear on the point, but because Clerics who hide significant aspects of their professional life from their institution are presumed to be hiding other things as well. Clerics of the Three Sisters working in occupied Norderenn have, in some documented cases, developed thieving skills out of practical necessity. The Hyerophancy is aware of this and has chosen not to make it a formal issue. That choice is not permanent.
Paladin/Cleric
The most institutionally powerful combination in the game, and the most institutionally fraught. A Paladin answers to their deity directly. A Cleric answers to their deity through the church hierarchy. When those two chains of command agree, a Paladin/Cleric is the most formidable religious actor a party is likely to encounter. When they diverge — when the institutional church wants one thing and the Paladin's direct divine calling demands another — this character is the contradiction made flesh.
The Church of Tar'amaan cultivates this combination deliberately for specific roles: Paladin/Clerics of Tar'amaan are the Archbishop-General's most reliable instruments because their divine calling and their institutional loyalty have been shaped toward the same ends since initiation. Encountering one as an adversary should feel different from encountering either class alone.
A Paladin/Cleric of the Three Sisters operating in Cadmano territory is, from the Church's perspective, a problem of the first order — someone whose divine authority and institutional backing are both pointed at the Church's interests. The Church does not ignore these characters. It prioritizes them.
Champion/Thief
The Code and the shadow work. A Champion's power derives partly from visibility — the Code must be witnessed to accumulate the reputation that gives the Champion weight. A Thief's effectiveness depends on the opposite. These are not incompatible, but they are in tension, and that tension requires the player to make decisions about how their Code is written.
A Code that contains explicit carve-outs for professional necessity — I do not lie except to protect an innocent; I do not steal except from those whose wealth was itself stolen — can accommodate Thief work. A Code without those carve-outs will eventually produce a violation, and then an atonement arc, and then a question about whether the Code was honestly constructed or strategically written with the violations already planned.
The more interesting version is the latter. A Champion/Thief whose Code keeps encountering the limits of what the Thief work requires is not a broken character — they are a character in genuine moral difficulty, which is where the most productive play tends to happen.
Fighter/Mage
The combination that the Order of Magnus finds most professionally interesting and the Church of Tar'amaan finds most alarming. A scholar capable of holding their own in the field is a researcher who can go places other researchers cannot. A warrior who can cast spells is someone who cannot be disarmed in any straightforward sense.
The Order cultivates Fighter/Mages as field operatives — agents who can pursue magical research in environments that would kill a pure scholar. The Church's position is more visceral: a magic-user is already dangerous; a magic-user who can also fight is a threat that cannot be neutralized by the usual means.
In the Known World's political landscape, Fighter/Mages tend to attract institutional attention from multiple directions simultaneously. They are valued as assets by factions that need capable field operatives, watched as threats by institutions that prefer their dangers separated and manageable, and occasionally approached as potential leadership by organizations that need someone capable of functioning in both worlds. Playing this combination means managing those competing claims on the character's time and allegiance.
Cleric/Mage
The theologically explosive combination. Arcane magic is, in the Church of Tar'amaan's framework, the corruption that ended the Second Era. Divine magic is the sanctioned alternative. A Cleric/Mage who serves Tar'amaan is not simply a heretic — they are a living refutation of the Church's foundational argument. The Church does not merely disapprove of this combination; it actively hunts for it among its own clergy, which is a reasonable institutional concern given that the combination would represent someone with both arcane capability and internal access to Church structures.
For Clerics of other faiths, the tension is less existential but present. The Three Sisters do not have a theological position against arcane magic — Ilya gave the First Gift freely — but the institutions that serve them operate in a world where arcane magic is politically dangerous, and a Cleric/Mage working within those institutions creates problems for everyone around them that a pure Cleric does not.
This combination is among the rarest in the Known World for reasons that have nothing to do with mechanical difficulty. Most people who could pursue it conclude, after reflection, that the institutional consequences are not worth what the combination provides.
Druid/Ranger (Warden Path)
The most institutionally coherent combination available, and therefore the most politically entangled. A Druid/Warden Ranger is someone the Hyerophancy has invested in twice over — as a formal Druid through the Compact, and as a Ranger who earned a Druid's personal recognition through demonstrated wilderness service. That relationship carries obligations that multiply rather than simply add.
The Hyerophancy values this combination as their most effective long-range operative: someone who can operate far outside Alvengaard without losing Druidic capability, who has the wilderness skills to reach places formal Druids cannot, and whose dual investment means two layers of institutional accountability. From the Hyerophancy's perspective, a Druid/Ranger Warden is a significant asset that requires significant management.
From every other faction's perspective, this character is the Hyerophancy's agent in a way that a pure Ranger or a stationary Druid is not. An adventuring Druid/Ranger Warden who claims to be acting independently is technically correct and practically unconvincing. The Hyerophancy knows where they are. Other factions assume the Hyerophancy knows where they are. Playing this combination means being read as an institutional actor even when operating on personal motives.
Sorcerer/Champion
Two competing external authorities: a patron's demands and a Code's tenets. Both are specific, both are enforceable, and they will eventually point in opposite directions.
Patrons tend to have opinions about Champions. A patron whose aims align with the Code finds the combination convenient — a Sorcerer with the Champion's combat capability and ethical predictability is a useful instrument. A patron whose aims conflict with the Code is a source of sustained pressure: demand the Sorcerer violate their Code, watch the atonement process impose its costs, repeat. A Sorcerer/Champion whose patron is genuinely hostile to the Code's values is playing a character whose two defining commitments are in active conflict, which is either a campaign premise or a path to losing levels in both classes.
The most productive version of this combination is one where the Code was written with the patron relationship in mind — where the player has thought through which patron demands the Code can accommodate and which it cannot. That preparation does not prevent conflict; it ensures the conflict is the kind that generates interesting play rather than the kind that terminates a character concept.
Combinations not listed here — Fighter/Thief, Ranger/Cleric, Bard/Thief, and similar professionally legible pairings — carry no specific Known World freight. They are people who learned two things. The chapter does not comment on every life choice.
