Dulanes Sapping Sensation

The target is wracked by an intensely unpleasant sensation. 

The target must make a Wisdom saving throw against the casters spell save DC. On a failed save the spell takes hold, the afflicted target has its movement speed halved and has disadvantage on Concentration checks for the duration they're effected. 

The target can re take the saving throw at the end of their turn or whenever they take damage. 

On a successfull save the spell fizzles to no effect. 

For each spell level above 2nd, the affected target takes 1d6 Psychic damage at the start of their turn (1d6 at 3rd level, 7d6 at 9th). This Psychic damage does not trigger the Wisdom saving throw re roll, the sensation overwhelming the mind of the target.
