Assassin's Burial

You touch a single humanoid corpse that died within the last hour, and imbue it with a foul enchantment. If a creature discovers the corpse that was unaware of it when the spell was cast, they must make a Charisma saving throw. If they fail, they are frightened of the corpse until the end of their next turn and will attempt to move so that they can no longer see it. If the subject attempts to reveal the presence of the corpse to any other creature, they immediately forget that they have detected the corpse for one hour. Each time this happens, the target can make a Wisdom saving throw. If they succeed, the spell ends after this instance of temporary memory loss.
