After he proceeded to call everyone in the game a noob for various reasons, I jumped in the chapel and the first thing he did was pop serenity. I teleported behind a wall in the chapel and casted mirror image. He went straight for the clones, his serenity wore off, then I finished him with WoF. After he called me a noob for beating him, he proceeded to make a claim, "Hacker! you just made 3 of yourself!"
Yes, that is right, he claimed I was a hacked because I used mirror image.
