  Casting this spell temporarily enchants a single weapon (or a stack of ammunition) with a magical bonus of +1 per three caster levels, to a maximum of +5 at 15th. This bonus does not stack with any other magical bonus the weapon may have. Magical weapons strike true against undead, outsiders and many other fiends.
