Small Shield +3

While holding this shield, you have a bonus to AC of +3. This bonus is in addition to the shield's normal bonus to AC.

Small shields are made of wood or metal, and cover little more than the hand or arm of the wielder. Some are bucklers, and require a hand to hold, and some allow for limited hand movement (enough to open a door or hold something, but not enough to make an attack or use the material or somatic components of a spell).
