Unarmed Strike (Ex)
At 1st level, a monk gains Improved Unarmed Strike as a bonus feat. A monk’s attacks can be with fists, elbows, knees, and feet. This means that a monk can make unarmed strikes with his hands full. There is no such thing as an off-hand attack Classes 1 for a monk striking unarmed. A monk can apply his full Strength bonus on damage rolls for all his unarmed strikes. A monk’s unarmed strikes deal lethal damage, although he can choose to deal nonlethal damage with no penalty on his attack roll. He can make this choice while grappling as well.
A monk’s unarmed strike is treated as both a manufactured weapon and a natural weapon for the purpose of spells and effects that enhance or improve either manufactured weapons or natural weapons.
The damage dealt by a monk’s unarmed strike is determined by the unarmed damage column on Table 1–2: Monk. The damage listed is for Medium monks. The damage for Small or Large monks is listed below.
