Greater Magic Weapon gives a weapon a +1 enhancement bonus per four caster levels on attack and damage rolls (maximum +5). An enhancement bonus does not stack with a masterwork weapon’s +1 bonus on attack rolls, and this does not allow a weapon to bypass damage reduction aside from magic.
Alternatively, you can affect as many as 50 arrows, bolts, or bullets. The projectiles must be of the same kind, and they have to be together (in the same quiver or other container). Projectiles, but not thrown weapons, lose their transmutation after they are used. Treat shuriken as projectiles, rather than as thrown weapons, for the purpose of this spell.
You can’t cast this spell on a natural weapon, such as an unarmed strike (instead, see Magic Fang). A monk’s unarmed strike is considered a weapon, and thus it can be enhanced by this spell.

Target: one weapon or 50 projectiles (all of which must be together at the time of casting)
