I just had a scary moment. I was in a lit mineshaft, like I usually am, when I started taking damage. My hunger bar was full, but I heard a ed off enderman. He was attacking me, but I swear he was invisible and I didn't even aggro one. Has this happened to anyone else?
lol There's a bunch of possibilities. It could be that it appeared in front of you just as you were about to hit something, but you accidentally hit it, and it went berserk on you, teleporting behind you and on top of you until you were dead, which could be really quick without good armor. It could also be that your cursor passed over his face in the distance, and he went berserk on you. Or maybe you made an enderman really angry in the past and he finally caught up to you.
Mind=Blown.
Endermen is probably like, "I would have gotten away with it too, if it wasn't for that meddling cat with the gif!"
Seriously though, did it occur to you that possibly...just...POSSIBLY, that he teleported the instant he hit you?
