Charm of Undeath

Your appearance takes on a deathly visage. You appear to be that of a fully sentient corpse, even by magical means of sight. You have advantage and expertise on all intimidation checks. In addition, those who wouldn’t be scared of an undead, such as another undead, a necromancer, or the like, experience the opposite. You have advantage and expertise with all persuasion checks with such targets. Furthermore, you are now able to attempt charisma checks against monsters who would otherwise be immune to these attempts. In these cases the previous effects apply, for both intimidation and persuasion. Undead will be reluctant to attack you, and will not do so unless directed to do so by whomever controls them.
