Cursed Blow

Crimson and black cursed energy explodes from your hand or weapon when you attack a creature. Make a melee attack against the target. On a hit, the target takes 3 Force damage, 1d4 necrotic damage, and one radiant damage. On hit the target can't heal for two turns.

The spell's damage increases by 1d4 when you reach 5th level (3 Force damage+1d4 Necrotic damage+1 radiant damage), 11th level (6 Force damage+1d4 Necrotic damage+ 1 radiant damage), and 17th level (9 Force damage +2d4 Necrotic damage+1+1d8 Radiant damage).
