seems to happen to often
I was at a depth 20 graveyard at the iron knight gate
I made the mistake of walking over the grave stones of every zombie in a small vicinity, but this is something I can manage on solo
However, I heard the phantom approaching but I couldn't see it
3 seconds later, I got hit by the phantom's gran faust charge and I die
It was in the freaking air but its charge was able to hit me
I raged quit afterwards and now im rage typing this post
Well you will be rage-upset by the simple rage-answer that the Phantoms are the only mob in the game that can noclip right to ya. Since the Graveyard has a lot of altitude changes, the Phantoms are graced with the pleasure of Z-axis hacking.
Did you know you can kill them as much as they can kill you? The funny thing is a lot of the time, they don't quite understand what's going on, so they attack much less often when they're noclipping through buildings and whatnot. If you see EVEN A GLIMMER of them hovering in the foreground, start swinging.
They just got some fat nerfing recently, BTW.
There. I hope my rage-answer will rage-calm you down a bit.
