Had a fight where my opponent only had a rotos left with no buffs and 1 health remaining and continued to hit him and he just wouldnt take any damage. He was hit by all of my champions at least 3 times each and still remained on 1 health and then proceeded to kill my team. The person I assume is the cheater goes by the account name of Makefile. I believe this needs looking into quickly because this could seriously mess arena up.
