Mass align fang makes multiple creatures’ natural weapons good-, evil-, lawful-, or chaotic-aligned, as you choose. A natural weapon that is aligned can overcome the damage reduction of certain creatures, usually outsiders of the opposite alignment. This spell has no effect on a natural weapon that is already treated as being aligned, such as the claw or bite attack of most demons.
You can’t cast this spell on a manufactured weapon, such as a sword.
When you cast this spell to make a natural weapon good-, evil-, lawful-, or chaotic-aligned, mass align fang is a good, evil, lawful, or chaotic spell, respectively.
