When you died in the viedo it had a Un-normal DeathMessage how did you do that It said like you died Lul Ugh
I sense rating abuse here. If it doesn't stop, 1 person to all 4 can be permanently forum banned. As for the kill aura and the ensuing conversations here, I have mixed feelings about it. It appears so, but there's always the chance some spam. If he is flailing, then he might not hack. If he isn't flailing, and goes in your direction, then it might be hacks. My opinion.
Yes, I'm confident enough to say that you don't hack, you killed him in 2 shots, and he didn't have armour on...
Thank you for your report IN1NJAI. Unfortunately the player does not look like he is hacking, you have no armor on, and it is very easy to see particle affects of potions. Locking and Archiving.
