You take on the aspect of Death itself. Your appearance chances to match your ideal visage of death. For the duration, your hitpoint maximum increases by 20, you gain 20 hitpoints, you have resistance to all damage, and your weapon attacks and cantrips deal an extra 2d6 necrotic damage. While this spell is in effect, you can choose to cast it again, expending another spell slot as normal. If you do, you mark a creature within 60ft for death. The creature must make a Constitution saving throw. On a failed save, they take 10d10 necrotic damage. On a success they take half damage.
