Veil of Undeath

You gain many of the traits common to undead creatures. You gain the following benefits for the duration:

• Your body appears sick and ghastly, as though you were a walking corpse. Undead with an Intelligence score of 6 or lower won't attack you except in self defense or when ordered to, and you are detected as an undead by a paladin's Divine Sense feature.
• You don't require air, food, drink, or sleep.
• You are immune to necrotic and poison damage. Whenever you are subjected to necrotic damage, you instead gain a number of temporary hit points equal to half the necrotic damage you would have taken.
• You are immune to the poisoned conditition, disease, and exhaustion.
