As heading states. . . Basically if you have AF, and you curse an opponent, when the opponent does damage to you they should do about 250 to 350 damage back on themselves per hit. However, in kemi arena, I found that this is NOT the case and there was no damage back on the player.
This would be an awesome ability if could curse a conq, he kb me, goes frenzy and then near kills himself. Too bad it's broken.
