Dark Vitality

Choose up to three creatures of your choice within range. A magical shield of blood surrounds them and coats their weapons.

Once before the spell ends, when the target makes an attack roll or a saving throw before the spell ends, they can roll a d8 and add the number rolled to the attack roll or saving throw. They also gain d8 temporary HP and gain resistance to fire, cold, or acid damage (caster's choice) for the duration.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional creature for each slot level above 3rd.
