Aspect of Pride

You imbue a creature with dark power. Choose a willing creature within range. That creature deals an additional 1d8 force damage with their attacks while they have more than half their maximum hit points. This comes with a cost; the creature reduces the damage they deal with attacks by 1d8 rather than adding 1d8 force damage while they have less than half their hit points. If the creature is under the effects of an Aspect of Gluttony spell, the creature's temporary hit points count as additional current hit points for the purposes of this spell.
