DnD5e Class-Specific Spellcasting Bonuses

DnD5e Class-Specific Spellcasting Bonuses is a utility module for the D&D5e system in Foundry VTT that enables class-scoped spellcasting modifiers using standard Active Effects.

Modifiers can be applied specifically to a source class (e.g., +1 DC to Wizard spells without affecting Cleric spells), making this an essential tool for:

• Multiclass characters with different power sources.

• Magic items that enhance a specific spellcasting class (e.g., Rod of the Pact Keeper).

• Subclass features that modify only one specific spell list.

• Temporary buffs that should not affect all spellcasting.

🌟 Features

• Class-Specific Modifiers: Support for both Spell Save DC and Spell Attack bonuses.

• Stacking: Bonuses from several effects on the actor or its items add together; disabled and suppressed effects are ignored.

• Dynamic Headers: Automatically updates the Spellcasting headers in the actor sheet to reflect class-specific totals.

• Non-Destructive: Uses libWrapper to recalculate values during data preparation without modifying core system data.

🛠️ How to Use

Add an Active Effect to a character or an item, with mode Add and the bonus as its value:

• Spell Save DC: flags.dnd5e-scoped-bonuses.class.spell.dc.[classname]

• Spell Attack: flags.dnd5e-scoped-bonuses.class.spell.attack.[classname]

For example, flags.dnd5e-scoped-bonuses.class.spell.attack.cleric with value 2 gives +2 to Cleric spell attacks. A spell receives the bonus when its source class matches the class name in the key.
