Conceal

A willing creature you touch with this spell has their living nature concealed from mundane and magical eyes. 

Undead that attack living things on sight, such as ghouls, no longer regard you as prey, instead seeing you as another undead, though they hold no special regard for you either; they will, however attack you if you attack them, or if they were given orders (i.e. "protect this area" or "attack any creature on sight").

This spell will foil divination spells equal to the casting level of this spell, giving false feedback about your creature type. Casting this spell each day for 100 days will cause the spell to be permanent until dispelled.

At Higher Levels: When this spell is cast using a spell slot of 3rd or higher, you can target an additional creature per spell level over 2nd.
