Harm

You unleash virulent magic on a creature you can see within range. The target makes a Constitution saving throw. On a failed save, it takes 🎲14d6 💀 Necrotic damage, and its Hit Points maximum is reduced by an amount equal to the 💀 Necrotic damage it took. On a successful save, it takes half as much damage only. This spell can't reduce a target's Hit Points maximum below 1.
