Armor Class

Every character (and items in some circumstances) have an Armor Class (AC). The base AC for a medium-sized character or item is 10. Bonuses and penalties are applied to this basic Armor Class to reflect the effects of armor, dexterity, etc.

Armor Class is an indication of how difficult it is to hit and do damage to a target.

Dexterity Modifier

Apply a character's dexterity modifier to the character's Armor Class any time that character can physically react to an attack. Characters lose their dexterity modifier when they are flat-footed, unaware of an attacker, or when they are restrained or otherwise rendered immobile.

Size Modifier

A character's size generates a standard Armor Class modifier, per this table:

Table:Size Modifier
Size AC/Attack Modifier
Fine +8
Diminutive +4
Tiny +2
Small +1
Medium 0
Large -1
Huge -2
Gargantuan -4
Colossal -8

Stacking Modifiers

AC modifiers of the same type do not stack, except:

  • Armor bonuses from armor and shields
  • Enhancement bonuses from armor and shields
  • Dodge bonuses
  • Circumstance bonuses

Touch Attacks

Touch attacks come in two types: melee touch attacks and ranged touch attacks. A character can score critical hits with either type of attack. A character's opponent's AC against a touch attack does not include any armor bonus, shield bonus, or natural armor bonus. The target's size modifier, dexterity modifier, and deflection bonus (if any) all apply normally.
