Calculating the AC of a character involves adding up the various sources of AC. Generally, most sources stack with each other, but not among themselves (with the exception of Dodge AC). For more information see Armor Class.

There are six types of AC in NWN2: Armor, Deflection, Dodge, Natural, Shield and Unarmored. Each subtype, other than unarmored, can be a base bonus or an enhancement bonus. Base bonuses stack and tend to be granted by persistent feats, while enhancement bonuses do not stack (with the exception of Dodge which stacks to +20) and are granted by spells, equipment and spell-like feats.

Against regular attacks all the types of AC are used for defense. Against touch attacks Deflection, Dodge and Unarmored are used for defense. When caught flat footed, Armor, Deflection, Natural and Unarmored are used for defense.

  • Every creature has a base 10 points of unarmored AC.

Dodge[edit | edit source]

Feats[edit | edit source]

  • Dodge: +1 AC against attacks from current target or last attacker and does not count towards the +20 limit.
  • Swashbuckler Dodge: +1/5 Swashbuckler levels against attacks from current target or last attacker and does not count towards the +20 limit.

Abilities[edit | edit source]

  • Dexterity bonus to AC: Dexterity modifier to a maximum of the Maximum dexterity bonus granted by armor (if armor is worn). Technically this is not dodge AC and does not count towards the +20 limit. However, since the dexterity bonus is lost or applied whenever a dodge bonus is lost or applied it is grouped with them here for practical purposes.
