Curse

When you take damage from an enemy, necrotic energy flows toward them, hitting them hard and placing a curse upon their mind. 

When hit, a target must make a wisdom saving throw. On a failure they take 2d8 necrotic damage and are cursed (pick on curse below). On a success they take half as much damage and are not cursed. The damage increases by 1d8 for every spell slot above level 2.

Curses

The target becomes Frightened. They may attempt to break the curse at the end of each of their turns.

The target becomes Blinded. They may attempt to break the curse at the end of each of their turns. 

The target becomes Restrained. They may attempt to break the curse at the end of each of their turns.
