In the video, WretchedCred is possibly using kill aura. As you can see, her head spins around to hit the players around her. Then while she is only on me, she goes to directly hit and kill Talon_Flame, and then she spins back to me. Also, later in the video, a person admits its her, and even proves its her. I believe both of the accounts should be banned. Proof:
Thank you for the report. The reported player has been banned. This thread as been moved to Reports - Banned.
