Blood Lacerate

You reach out and quickly shift a target’s blood in their veins, causing lacerations to appear. The target must succeed on a Constitution Saving Throw or take 1d6 necrotic damage and suffer half as much damage on their next turn.

This spell’s damage increases when you reach certain levels: 5th level (2d6), 11th level (3d6), and 17th level (4d6).
