Wisdom Spell


Why cant I cast a wisdom spell , If I try to cast one It either does not get cast or I get a banner come up saying that it can only be used on an attack , I even use it after sending a purifying, that is what I got on an attack of 41 LS , if that is not an attack I dont know what is ??
THis has been the fault for all of this world but now it is needed more and more to work.
