-Most damage-enhancing properties add bonus damage of a certain type, often equal to base damage, to the object when used as a weapon - for example, a flaming [[long sword]] would deal (1d8 + enchantment) physical damage and (1d8 + enchantment) fire damage versus small monsters. This includes specific non-weapon objects that are also valid for weapon attacks, e.g. [[boots]] for [[kick]]ing attacks and [[gloves]] for unarmed (i.e. bare-handed) attacks. Some of these properties also have a weaker form as well, which usually deals +2d6 damage instead.

This includes specific non-weapon objects that are also valid for weapon attacks, e.g. [[boots]] for [[kicking attack]]s and [[gloves]] for [[claw attack]]s, [[bare-handed combat]] and the like. Some of these properties also have a weaker form as well, which usually deals +2d6 damage instead.
 These bonuses only apply if the object is a valid weapon (e.g. a flaming [[newt]] [[corpse]] grants no bonuses), and are additive with other attack bonuses rather than multiplicative.
