Sympathy

As a reaction to being hurt, you lash out raking the attackers nervous system with sympathetic psionic vibrations. As a reaction to an attack you can see within 30ft, you can use your reaction to force the attacker to make an Intelligence saving throw. On a failed save, the target takes 1d8 psychic damage per 2 spell levels/charges spent. The maximum damage this reaction can deal is equal to the damage taken that prompted the reaction.
