=Damage Mechanics=
==Overview ==
Under the hood, superficially similar damage bonuses can be implemented in very different ways.
For example, the {{RarityItem|Callous Glow Ring}} and the {{RarityItem|Caustic Band}} are both rings that give 2 bonus damage. However, their damage bonuses are implemented using two different functions and wind up behaving quite differently.
Understanding how these different functions work will help explain the oftentimes unintuitive damage mechanics in Baldur's Gate 3.

Below is a breakdown of the different functions used to apply damage bonus effects.

|-
|<code>WeaponDamage()</code>
| rowspan="3" |'''Weapon rider'''
| rowspan="3" |The basic, well-behaved damage bonuses are implemented with this function. The bonus will apply to ''only'' the triggering attack and nothing else.
| rowspan="3" |{{DamageText|2|Acid}} from {{RarityItem|Caustic Band}}
|-
|<code>CharacterWeaponDamage()</code>
|-
|<code>CharacterUnarmedDamage()</code>
|-
|<code>DamageBonus()</code>
|'''Damage rider'''
|Damage bonuses using this function will add their damage to each independent damage instance. When combined with effects that use <code>DealDamage()</code>, a single attack can create numerous independent damage instances so <code>DamageBonus()</code> effects can potentially apply their damage many times per attack.
|{{DamageText|2|Radiant}} from {{RarityItem|Callous Glow Ring}}
|-
|<code>DealDamage()</code>
|'''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. <code>DealDamage()</code> creates a separate damage instance that can be independently boosted by applicable <code>DamageBonus()</code> sources. In certain scenarios, '''DRS''' effects can trigger each other, creating far more damage instances than might be expected.
|{{DamageText|1d8|Physical}} from {{SAI|Colossus Slayer}}
|}
The interaction between the different types of damage bonuses can be summarized as follows:
* '''Weapon rider''' bonuses do exactly what they say -- nothing more, nothing less.
* The effect of '''damage riders''' is multiplicative with the number of independent damage instances. An attack with 2 extra damage instances from '''damage rider source''' effects will apply any '''damage riders''' 3 times.
* The number of damage instances can grow exponentially with the number of '''damage rider sources'''. For example, if you {{SAI|Sneak Attack}} a {{Cond|Burning}} target with the {{RarityItem|Firestoker}}, you will create 4 independent damage instances: the base attack, the sneak attack, '''Burned Alive''' triggered by the base attack, and '''Burned Alive''' triggered by the sneak attack. If you add {{SAI|Phalar Aluve: Shriek}}, this will increase to 8 '''DRS''' instances since Shriek will be triggered by each of the 4 preceding instances.

== Weapon riders ==
This category of damage increasing abilities applies only to your weapon (or unarmed) attack damage and nothing else.
One weapon attack will apply each '''weapon rider''' exactly once.
Unlike the two other classes of damage boosts, they are very well-behaved and won't interact with other damage boosts to produce unexpected results.

'''Weapon riders''' are far too numerous it exhaustively list. Instead, here is a small sample of damage boosts of this category:
* +10 damage from Great Weapon Master
* Bonus damage from {{Cond|Arcane Synergy}}
* {{DamageText|1d4|Fire}} damage from a fire-dipped weapon
If a damage boost is not listed in one of the sections below, assume that it is a '''weapon rider''' by default.

== Damage riders ==
Unlike '''weapon riders''', '''damage riders''' can "ride" on damage sources other than weapon or unarmed damage.
This makes them more flexible and potentially abusable than basic '''weapon riders'''.
In particular, when combined with one or more '''damage rider source''' effects, a '''damage rider''' can potentially apply multiple times to a single attack, effectively multiplying their provided damage bonus.

This is a comprehensive list of all the '''damage riders''' in the game which can be acquired by the player. There are other '''damage riders''' 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.

The top 5 '''damage riders''' in the above list are '''universal'''. They will apply to any damage instance, even ones '''detached''' from a spell or attack. All the other '''damage riders''' involve conditions like <code>IsSpell()</code> or <code>IsMeleeAttack()</code> so any damage instance that is not a part of a spell or weapon attack cannot be boosted by these non-'''universal damage riders'''. Status effect damage like {{Cond|Simple Toxin}} is an example of damage '''detached''' from any attack or spell that can only be boosted by '''universal damage riders'''. See below for a more detailed discussion of '''detached''' damage instances.

== Damage rider sources ==
Damage bonus implemented with <code>DealDamage()</code> (i.e. '''Damage rider sources''') are the underlying cause for much of the unintuitive damage mechanics in Baldur's Gate 3.

All attacks or damaging spells are implemented using <code>DealDamage()</code>, so any damage bonus implemented using that same function will behave somewhat like an independent attack or spell.
Importantly, this means that '''damage rider sources''' can potentially trigger each other causing an exponential explosion in the number of damage instances (with the right combination of '''DRS''' effects).
As previously stated, adding '''DRS''' effects to an attack will also multiple the effectiveness of '''damage riders'''.

=== Exponential behavior when combining DRS effects ===

=== Attached vs detached instances ===
There are two sub-categories of '''DRS''' effects that determine how they interact with '''damage riders''': '''attached''' and '''detached'''.
*A '''DRS''' effect '''attached''' to an attack or spell will be grouped and indented under a heading like "X used Main Hand Attack" or "X cast Fire Ball". Most '''DRS''' effects will be attached to the triggering attack.
*A '''detached''' instance will appear separately in the damage log, not grouped with the triggering attack. '''DRS''' effects wind up detached because they call <code>DealDamage()</code> indirectly. For example:
**When standing in a Burning surface, the {{RarityItem|Amulet of Elemental Torment}} will effectively add a {{DamageText|1d4|Fire}} '''DRS'''. The amulet's effect doesn't call <code>DealDamage()</code> directly, but instead calls <code>ApplyStatus(BURNING)</code>. On application, the {{Cond|Burning}} status effect calls <code>DealDamage()</code> immediately.
**To apply its {{DamageText|1d4|Thunder}} damage, the {{RarityItem|Punch-Drunk Bastard}} calls <code>CreateExplosion()</code> which then calls <code>DealDamage()</code>.
The practical difference between '''attached''' and '''detached''' '''DRS''' sources is that some '''damage rider''' effects will not apply to '''detached''' sources. For example, the {{DamageText|1d4|Fire}} damage instance from the Amulet of Elemental Torment is detached from the spell cast and thus will not get boosted by '''damage riders''' like the [[Potent Robe]] or [[Elemental Affinity: Damage]] which explicitly apply only to spell/cantrip attacks. It will, however, be boosted by more '''universal''' damage riders like [[Arcane Charge (Condition)|Arcane Charge]].

=== DRS effects for spells ===
There are a limited number of '''DRS''' effects that work with spells or cantrips, particularly '''attached''' effects. However, many spells have built in ways of dealing multiple damage instances. For example:
* Multi-hit spells like {{SAI|Magic Missile}} or {{SAI|Scorching Ray}} deal separate damage instances for each projectile.
* Spells with multiple damage types like {{SAI|Ice Knife}} or {{SAI|Flame Strike}} deal separate damage instances for each damage type.

== Glossary ==
There is not necessarily any community consensus regarding the following terms and they may only make sense within the context of this article.

* '''Attached''': A damage instance attached to an attack or spell in the damage log.
* '''Damage rider''': A damage bonus implemented with <code>DamageBonus()</code>. These bonuses can potentially apply many times in a single attack since they boost each independent damage instance.
* '''Damage rider source''': A damage bonus implemented with <code>DealDamage()</code>. These bonuses create an independent damage instance instead of adding damage to an existing instance.
* '''Detached''': A damage instance not grouped with the triggering attack or spell in the damage log.
* '''DRS''': See '''damage rider source'''
* '''Universal damage rider''': A '''damage rider''' that doesn't have conditions like <code>IsSpell()</code> and can boost even '''detached''' damage instances.
* '''Weapon rider''': A damage bonus implemented with <code>WeaponDamage()</code> or similar functions. These bonuses are well-behaved and will only ever apply once per attack.
