Destroy Balance

Once a day, the user is able to focus on the darkness of ones soul in order to cast either a veil of darkness by sacrificing a third of ones hit points. The spell can be cast again after a long rest and 3 hours of meditation focusing on reconnecting the balance. 

Veil of Darkness: User can select any living/non-living creature and on success, rolls a 1d20 to determine amount of damage inflicted upon the creature. Following the initial attack, the user will then roll 1d8 to determine how much damage is inflicted each round until either the creature(s) are killed, or the user is knocked down/unconscious.

At 7th, 10th, and 13th level, add 1d4 to the initial damage die count and at 13th level the user can roll a 1d100 to determine if hit points are needed to be sacrificed. (51 and above is a success in keeping all hit points, 50 and under required one fourth of the hitpoints to be used) If the user does not choose to use a 1d100, the player can sacrifice half their hitpoints to guarantee a successful hit.
