Armor Class

Unattended objects are easier to hit than creatures because they don’t usually move, but many are tough enough to shrug off some damage from each blow. An object’s Armor Class is equal to 10 + a modifier due to its size (see Table 11–12: Size and Armor Class of Objects) + its Dexterity modifier. An inanimate object has not only a Dexterity of 0 (–5 modifier) but also an additional –2 penalty to its AC. Furthermore, if a creature takes a full action to line up a shot, it automatically hits with a melee weapon and gains a +5 bonus to an attack roll with a ranged weapon.
