View source for Damage roll

When a creature attacks another creature in NWN2, that attack is divided into three phases:
*The [[Attack roll|Attack Roll]] to determine if the attack hits its target.
*The [[Critical hit|Critical Hit]] confirmation roll, if the attack hits and the attack roll threatens a critical hit, to determine if the attack was a critical hit.
*The damage roll to determine how many [[HP|hitpoints]] a creature loses from the attack.
The basic damage roll consists of:

[[Ability modifier|Ability Modifier]] affecting damage + [[weapon|base weapon damage]]+ [[Enhancement bonus]] + Other damage modifiers

In the case of a critical hit this formula becomes:

(Ability modifier affecting damage + base weapon damage + Enhancemnet bonus + damage modifiers that are multiplied on a critical hit) x Critical Hit Multiplier + damage modifiers that are not multiplied on a critical hit+ Massive Criticals/[[Overwhelming Critical]] damage.

There are many [[Damage type|types of damage]] in D&D, and an attack can inflict several types of damage.  In general most of the damage inflicted will be of the same type as the weapon.  For the most part the type of damage is not important, however [[Damage Immunity]] will reduce a fraction of damage of a specified type and [[Damage resistance|Damage Resistance]] will reduce a fixed amount.  [[Damage reduction|Damage Reduction]] will reduce all physical damage by a fixed amound unless a certain criteria is met.

== Ability Modifier Affecting Damage ==

In general this [[Ability modifier|Ability Modifier]] will be the creature's [[Strength]] modifier. Although if a creature has [[Combat Insight]] and a higher [[Intelligence]] modifier than Strength modifier, the intelligence modifier will be used instead. The amount of modifier damage a creature can add to its damage roll is modified by several factors.
For melee weapons:
*If the weapon is of the same [[Size|size category]] as the creature or larger and the creature has nothing in its off-hand (i.e. the weapon is wielded two-handed), the creature will add 1.5 x its ability modifier (rounded down) to damage.
*If the weapon is a [[Light weapon|light weapon]] for the creature, or there is something in the creature's off-hand, the creature will add its full ability modifier to damage.
*If the weapon is being wielded in the off-hand of the creature, the creature will add half its ability modifier (rounded down) to damage.
With ranged weapons, if the weapon has the [[mighty]] property, the creature may add its ability modifier up to the value of this property to its damage roll.
With thrown weapons and slings, the creature may add its full ability modifier to its damage roll, with the exception of [[Shuriken|shurikens]] (which do not get any ability modifier damage).

== Damage that is Multiplied on Critical Hits ==

As a rule of thumb most constant damage is multiplied on critical hits and most random damage is not multiplied on a critical hit.  Damage that is multiplied on a critical hit includes:
*Ability modifier damage
*Base weapon damage (dice are rolled multiple times, not rolled once and multiplied)
*Enhancement bonus damage
*([[Epic Weapon Specialization|Epic]]/[[Greater Weapon Specialization|Greater]]) [[Weapon Specialization]]
*[[Favored Enemy]] bonus
*[[Bane of Enemies]]
*([[Improved Power Attack|Improved]], [[Favored Power Attack|Favored]], [[Enhanced Power Attack|Enhanced]], [[Supreme Power Attack|Supreme]]) [[Power Attack]]
*([[Epic Divine Might|Epic]]) [[Divine Might]]
*[[Swashbuckler#Insightful Strike|Insightful Strike]]
*[[Arcane Archer]] Enhance Arrows damage
*[[Stormlord]] Enhancement Bonus
*Smite ([[Smite Good|Good]]/[[Smite Evil|Evil]]/[[Smite Infidel|Infidel]])
*[[Divine Favor]]
*[[Prayer]]
*[[War Cry]]
*[[Inspire Courage|Courage Inspiration]]

== Damage that is not Multiplied on Critical Hits ==

The following are sources of damage that are not multiplied on a critical hit.
*[[Precise Strike]]
*[[Flourish]]
*[[Stormlord]] elemental damage bonuses
*Weapon bonus damage (both constant and random)
*[[Storm Avatar]]
*[[Flame Weapon]]
*[[Blades of Fire]]
*[[Sneak attack|Sneak Attack]]
*[[Bleeding Wound]]

== Damage That Does Not Work Against Enemies Who Are Immune to Critical Hits ==

*[[Sneak attack|Sneak Attack]] ([[Epic Precision]] allows a character to inflict half damage with sneak attacks against these enemies)
*[[Swashbuckler#Insightful Strike|Insightful Strike]]

== Damage That Is of the Same Type as the Weapon Being Used ==

Some damage will be of the same type as the weapon being used.  These sources include:
*Ability modifier damage
