Clutch of Orcus

The caster creates a magical force that grips the subject's heart (or similar vital organ) and begins crushing it. The target must succeed on a Constitution saving throw or the victim reacts as if having a heart attack, is paralyzed and takes 2d4 points of necrotic damage per round for the duration. At the end of each of its turns, the target can make another Constitution saving throw. On a success, the spell ends on the target.

If the victim dies as a result of this spell, his chest ruptures and bursts, and his smoking heart appears in the caster's hand.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can target one additional humanoid for each slot level above 3nd. The humanoids must be within 15 feet of each other when you target them.
