Damage Mechanics

Overview

Function	Term	Comment	Example
WeaponDamage()	Attack damage	The basic, well-behaved damage bonuses are implemented with this function. The bonus will apply to only the triggering attack and nothing else.	2Acid from Caustic Band
CharacterWeaponDamage()
CharacterUnarmedDamage()
DamageBonus()	Damage rider	Damage bonuses using this function will add their damage to each independent damage instance. When combined with effects that use DealDamage(), a single attack can create numerous independent damage instances so DamageBonus() effects can potentially apply their damage many times per attack.	2Radiant from Callous Glow Ring
DealDamage()	Damage rider source (DRS)	This function is used by all damaging attacks, spells, and conditions to deal their damage, but some damage bonuses also use it. DealDamage() creates a separate damage instance that can be independently boosted by applicable DamageBonus() sources. In certain scenarios, DRS effects can trigger each other, creating far more damage instances than might be expected.	1d8Physical from  Colossus Slayer

This is a comprehensive list of all the damage riders in the game that use DamageBonus() which can be acquired by the player. There are other DamageBonus() effects exclusive to certain enemies or attached to items not available in the game (outside of cheats). These effects are excluded from the list below.

If a damage type is not specified, the damage bonus will inherit the type from whatever damage source it is applied to.
