Divine Ichor

Prerequisite: You can only cast this spell while you are at or below 25% of your maximum hit points.

Your celestial and vampiric blood surge through your body, forcing divine ichor through your veins. For a moment, golden radiance erupts from beneath your skin, threaded with black and crimson energy.

Each creature of your choice within 20 feet of you must make a Dexterity saving throw. On a failed save, a creature takes 4d8 Radiant damage + 4d8 Necrotic damage, or half as much damage on a successful save.

After the eruption, you regain hit points equal to 2d8 + your spellcasting ability modifier.

Once you cast this spell, you cannot cast it again until you finish a long rest.
