Protection from Evil and Good

Until the spell ends, a willing creature you touch gains protection against certain types of creatures: celestials, elementals, fey, fiends, undead, and voidborns.

This protection grants several benefits. Creatures of these types have disadvantage on attack rolls against the target. The target cannot be frightened, charmed, or possessed by them. If the target is already frightened, charmed, or possessed by these creatures, it has advantage on any new saving throw against the relevant effect.
