I'm being invaded by High level dark spirits

Hi everyone =)

Well I have been playing dark souls for a while. I've finished it a couple of times actually a lot of times on Xbox, now I got the PS3 version because I want to play online and ooohhh my we got a problem here.

I started a new class, a cleric, lvl 15 more or less i don't remember quite well. And while in Undead Burg I get invaded by a dark spirit. Ok no problem maybe I can handle it. Unfortunately that guy had:

2 ultra great swords
Fully upgraded Electric Zweihander
cloranthy ring or mask of the child
dragon head
wrath of gods (infinite?)
smough's armor combined with some advanced armours

And one day one of these guys used some kind of infinite bortex hability that kept me and my proyectiles away from him.

I'm very very upset, angry, pissed off, etc... Why am I getting invaded by people with all that ridicolous stuff? maybe they are lvl 200 - 170 - 180 who knows? O.O

This is unfair. OHH ONE MORE THING!!!

They love to backstabbing me with those fully upgraded weapons >.<

Cheers!! =)

They're griefers using late game gear glitched over to a new character to just kill beginners for **** and giggles. Also, that dragon vortex is another glitch. When you see them turn away POISON them. They require stamina, and poison has an odd stamina draining effect.

wow great idea. so they are cheaters that's not supposed to happen. thanks
