Coliseum battle glitch : KO Submissions

Ok, heres something i found out while battling in the coliseum in Moraden.
In the clan battle arena where it's raining down um red stuff (what is it anyway), stand in the entrance so u can attack, have someone hit you with a magic skill ( i got hit withfire, but i dont think it matters), and immediately after you take damage step back like half a step. If done correctely you should still be able to attack but people cannot attack you. This works until you move from the spot.

Can premium members say yay or nay to this being moved to a confirmed section.
