Eye of Accuracy (Magic Eye)

This flat, coin-sized piece of polished human bone is shaped like a staring eye. Its back bears a single word inscription, a command word (typically “Larth”). If this is spoken as the eye is touched to any one weapon, and the weapon is then thrown or fired at a target, it strikes at +4 to its attack roll. Used in this way, the weapon counts as a +4 magical weapon for determining what it can hit. Damage is augmented by a +2 bonus.
The eye vanishes with one use, but the weapon it enchants continues to have both of its combat bonuses for two rounds. Of course, a thrown sword can well be used against its original wielder! This does not mean that magical weapons can temporarily augment existing powers; the enchantments cancel each other out, rendering affected magical weapons normal for 1d4 rounds.
