Thank you for expressing interest in the RP. I will only allow bloodbending if he can't control the blood in other peoples bodies (Which is a solid 1 hit kill). If he must control other peoples blood, then he should only be able to control blood that's been exposed to air. Necromancery...? Imma need details. Lots of them. Because like hell there's going to be an army of flesh eating zombies roaming around the school.
