This spell gives a weapon an enhancement bonus to attack and damage of +1 per three caster levels (maximum +5). An enhancement bonus does not stack with a masterwork weapon’s +1 bonus on attacks.

Alternatively, the character can affect up to fifty arrows, bolts, or bullets. The projectiles must all be of the same type, and they have to be together in one group (such as in the same quiver). Projectiles (but not thrown weapons) lose their transmutation when used.

If the character is a good cleric, the cleric of a good deity, or a paladin, the weapon is considered blessed, which means it has special effects on certain creatures.
