Again a world first for soloing as a warrior.
Could have done it months ago, gear slightly improved.
If it wasn't for the constrictor tentacle @ beginning of phase 2, this would be peace of cake, not relying on RNG luck.
So that's why i refused to try this boss the last months.
Guide is in the Youtube Information.
Gear is ilvl408, souldrinker+fetish are a must have.

Tracklist:
Immediate Music - lords of the realm
Immediate Music - Def Con
Immediate Music - a thousand deaths
