Was sitting in his room camping Yelwinz when he popped on me. Max hit me for 410, flurries, and harm touched for 1001. His curse was easily cured by 2-3 shots of bard song.
Needless to say, I hotfooted it out of his room and faded him off.
He isnt a PH for cursed He's a 6 day spawn and when you kill all 10 TM's in the basement (including this one) a glyph covered serpent spawns, after that dies, vhyzh dra the exiled spawns, then after he dies, vhyzh dra the cursed spawns.
Yes he basically IS the PH for cursed as ALL of the other mobs you need to kill to initiate cursed cycle are on 2 hr timer, this is the only one on 6 day timer.
Since you're being picky, it's 7 TMs, 1 Warden, and 2 Rzoths that you need to kill, not 10 TMs.
He casts Balance on players fighting him. It is a cure type spell, and took me 3 casts of remove curse to cure it. The "curse" seems to inhibit heal dots and normal regen, and regen type spells. He hits ahrd too, I think 310 per hit, he also gates. Im not sure if Balance is a proc or a spell he cast. I would gadge him on the level of a ragefire type encounter, but without the AEs. We took him down with 32 players all 50+.
