==Damage reduction==
Damage reduction is the ability of a [[creature]] to effectively "shrug off" or instantly regenerate [[damage]] done to it. Damage reduction can reduce damage to 0 but not below 0.

===Defeating damage reduction===
This ability is not a perfect protection as it is possible to still cause enough damage to overwhelm the ability, or bypasses it if certain conditions are met. The creature takes normal damage from energy attacks (even nonmagical ones), [[spells]], [[spell-like ability|spell-like abilities]], and [[Supernatural ability|supernatural abilities]].

===Notation===
Damage reduction is written as "value/type" where the "value" is a numeric number stating up to how much damage can be ignored each time the creature is injured and "type" is the condition which can bypass the ability.

'''e.g.'''<br />
A creature with damage reduction 10/[[silver]]:
*is struck with a [[weapon]] for 5 points of damage.
**if the weapon is not made of silver, all the damage is completely ignored.
**If the weapon is made of silver, the creature receives the full 5 points of damage.
*is struck with a weapon for 17 points of damage.
**if the weapon is not made of silver, the creature receives 7 ''(17-10)'' points of damage.
**If the weapon is made of silver, the creature receives the full 17 points of damage.

====Types====
There are numerous different conditions which damage reduction can be bypassed with:
*weapon [[material]]:
**[[Cold iron]]. Creatures such as [[fey]] or [[demon]]s.
**[[Silver]]. Were-creatures or [[undead]].
**[[Adamantite]]. Golems and other metal creatures.
*[[Alignment]]: [[Good]], [[evil]], [[lawful]], [[chaotic]] etc. Usually this is not a specific alignment like [[chaotic neutral]].
*[[Damage type]]: [[piercing]], [[bludgeoning]], or [[slashing]] damage etc.
*[[Enchantment]]:
**[[Magic]]: Any weapon with at least a +1 magical [[enhancement bonus]] on attack and damage rolls. Such creatures’ [[natural weapon]]s (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction.
**Epic: Magic weapons with at least a +6 enhancement bonus. Such creatures’ natural weapons are also treated as epic weapons for the purpose of overcoming damage reduction.
*Multiple conditions:
**OR conditions: A few creatures are harmed by more than one kind of weapon. A weapon of either type overcomes this damage reduction.
**AND conditions: A weapon must be both types to overcome this damage reduction. A weapon that is only one type is still subject to damage reduction.

Some damage reduction has no bypass conditions. This is written using - (e.g. 5/-) and means it is always in effect. (See [[Damage resistance|Damage Resistance]].)

Ammunition fired from a projectile weapon with an enhancement bonus is treated as a magic or epic weapon for the purpose of overcoming damage reduction. Similarly, ammunition fired from a projectile weapon with an alignment gains the alignment of that projectile weapon (in addition to any alignment it may already have).

===[[Stack]]ing===
If a creature has damage reduction from more than one source, the two forms of damage reduction do not stack. Instead, the creature gets the benefit of the best damage reduction in a given situation.

'''e.g.'''<br />
A creature with damage reduction 10/silver and 5/evil is struck with a weapon for 15 points of damage.
*if the weapon is neither made of silver nor evil-aligned, the creature receives 5 ''(15-10)'' points of damage.
*If the weapon is only evil-aligned, the creature still receives only 5 points of damage.
*If the weapon is only made of silver, the creature receives 10 ''(15-5)''points of damage.
*if the weapon is made of silver and evil-aligned, the creature receives the full 15 points of damage.

===Preventing additional attack [[effect]]s===
Whenever damage reduction completely negates the damage from an attack, it also negates most special effects that accompany the attack, such as injury type [[Poison_(effect)|poison]], a [[monk]]’s [[stunned|stunning]], and injury type [[disease]]. Damage reduction does not negate [[touch attack]]s, energy damage dealt along with an attack, or [[Level/ability drain|energy drains]]. Nor does it affect poisons or diseases delivered by inhalation, ingestion, or contact.

Attacks that deal no damage because of the target’s damage reduction do not disrupt spells.

===Sources===
*Classes
**[[Barbarian]]s gain 1/- [[Barbarian#Damage_reduction|damage reduction]] at 7th [[class level|level]]. At 10th level, and every three barbarian levels thereafter (13th, 16th, and 19th level), this damage reduction rises by 1 point. At 28th level the final value is 8/-.
**[[Monk]]s gains [[Monk#Perfect_self|10/magic damage reduction]] at 20th level.
**[[Warlock]]s gain 1/[[cold iron]] [[Warlock#Damage_Reduction|damage reduction]] at 3rd level. At 7th level, and every four warlock levels thereafter (11th, 15th, and 19th level), this damage reduction rises by 1 point. At 27th level the final value is 7/cold iron.
**[[Dwarven defender]]s gains 3/- [[Dwarven Defender damage reduction|damage reduction]] at 6th level. At 10th level, this damage reduction rises to 6/–.
**[[Divine champion]]s gain the [[divine wrath]] 1/day at 5th level. When active, this feature provide 5/- damage reduction for a number of [[round]]s equal to her [[charisma]] [[ability modifier|modifier]] (minimum 1 round).
**[[Favored Soul]]s gain 10/[[cold iron]] or 10/[[silver]] at 20th level.
**[[Spirit Shaman]]s gain 5/[[cold iron]] at 20th level.
*Feats
**The [[Fey Skin]] feat provides up to 5/[[cold iron]] (1 for each [[Fey Heritage]] feat taken).
**The [[Greater Resiliency]] feat adds 1/- damage reduction. (prerequisite: damage reduction of 1/-)
**The feat [[Epic Damage Reduction]] adds 3/- damage reduction.
*Other
**Armor crafted from [[adamantine]] gains 1/- to 3/- damage reduction, depending on the type.
**Some spells ([[Stoneskin]], for example) and feats ([[Rescue]]) can provide temporary damage reduction, as can some magical items when equipped.
====Bypass sources====
*A [[monk]]'s [[Monk#Ki_Strike|ki strike]] feature grants their unarmed attack enhancements to meet some damage reduction conditions. At 4th level their unarmed attacks are treated as magic weapons, at 10th level they are treated as lawful and at 16th level they are treated as adamantine. Each upgrade does not replace the previous effect so at 16th level a monk's unarmed attack count as a magical, law-aligned adamantite weapon.
*Spells may temporarily enhance attacks to meet the conditions of damage reduction, while weapons also provide more permanent methods.

==NWN comparison==
*NWN's implementation of damage reduction only required a specific magic enchantment (e.g. +1 or +7 etc) to bypass damage reduction. This also included basic bonuses to-hit or damage not from enhancement (which provides both to-hit and damage bonuses).
