I was about to attempt it solo in-era on TLP at lvl 59. I got cold feet and brought along a 60 Warrior and 51 Druid for spot heals. Very glad we did this as I don't imagine I could have solo'd this fight. Bring a coupld of friends. Don't get caught off-guard by the third spawn lifetapping and HT.
This one started off the fight by tapping me but after the first tap of 200 and either harm touch or a DD for 800 my pet got in there and beat it senseless I landed undead slow on it and then it was just a cake walk. added in my dotz for some entertainment and sat back and watched him drop my symbol
Just did it today and verified that it is a tortured soul, not tormented. All 3 were soloable. First and last summoned, blood of thule stuck each time on all 3 mobs.
