Small Shield +2

Small Shield +2 is a shield which offers an armor class bonus of 3, but it offers no protection against arrows, so it has -3 penalty to missile weapons to compensate for this. The shield has a weight of 3 lbs. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition.

In-game description
"Despite the effectiveness of the enchantments on this shield, it is otherwise nondescript and defies precise identification. Such standardization makes it likely that it is from the militia of some forgotten barony, though it is hard to be certain."
