Clutch of Azgoth

Magical force grips the subject’s heart (or similar vital organ) and begins crushing it. The victim reacts as if having a heart attack, is paralyzed and takes 2d6 points of necrotic damage per round. Concentration is required to maintain the spell each round. A conscious victim gains a new saving throw each round to end the spell.

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 3rd. The humanoids must be within 20 feet of each other when you target them.
