Dodge bonus

From NWNWiki

Dodge is a bonus to armor class resulting from physical skill at avoiding blows and other ill effects. Bonuses of this type apply against touch attacks. Dodge bonuses stack with bonuses of other types, and they stack with each other up to a cap of +20. This cap applies to the net bonus, so dodge bonuses in excess of +20 can be used to offset a negative dodge modifier, such as the result of a taunt.

Any situation or effect that negates a character's dexterity bonus to AC also negates any dodge bonuses the character may have. (Note that wearing armor may reduce the dexterity bonus but does not negate it.) The uncanny dodge and defensive awareness feats may restore a character's dexterity bonus in these situations, but they do not restore the dodge bonus. The most common situation that negates the dexterity bonus is being flat-footed.
