Toll the Stricken

You reach out your hand toward a target in range, and a spectral ray of toxic energy leaps from your palm to the target. The target must make a Constitution saving throw or be poisoned until the end of your next turn. If a target is already poisoned or diseased before they fail their save, they must take 1d8 necrotic damage and the poisoned effect extends for one round.

The spell’s damage increases by one die when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
