Tooth of the Wyrm

2nd-Level Necromancy

Casting Time: 1 action
Range: Touch
Components: V, S, M (a dragon’s tooth)
Duration: Concentration, up to 1 minute

Your touch opens a magical wound in a creature you try to touch. Make a melee spell attack against the target. On a hit, the target takes 1d4 necrotic damage. Until the spell ends, the target takes necrotic damage at the start of each of its turns. The necrotic damage increases by 1d4 each subsequent round, dealing 2d4 necrotic damage on the target’s first turn after being hit, 3d4 on the target’s second turn after being hit, and so on.

At the end of each of its turns, the target can make a Constitution saving throw. On a success, the spell ends. A lesser restoration spell cast on the target also ends the spell.
