Guild Wars 2

After dying once to the Sovereign Eye, I went back to the boss and found it invulnerable, which does not go off even after a period of time.

I have finally found a way to prevent the ambush, which is to kill all mobs around the area including the Abomination at the tomb entrance, and also by leaving the Plaguebearer as the last monster to kill along the path. I only escorted the npcs after the mobs were cleared and yep, there was no more ambushes.

Wtf PS difficulties.

Is it just me or is the lvl 80 PS “Against the Corruption” really unsoloable? I keep getting swarmed at the ambush part, and when I try to pull just 1 mob over, the whole group chases after me. Any tips on how to avoid the ambush (Coz I saw a video on youtube, and there wasn’t any ambush==) or how to simply kill the group of mobs?
I’m a Thief, btw.
