Eiha

You snap your fingers, summoning a burst of dark, cursed energy beneath a target you can see within range. The target must make a Dexterity saving throw. On a failure, they take 3d8 necrotic damage and are cursed with sluggishness; their movement speed is reduced by 10 feet until the end of their next turn. On a success, they take half damage and their speed is not reduced.
