Hellfire Ramparts - Omor the Unscarred solo'ed

The second boss of Hellfire Ramparts, Omor the Unscarred, doesn't stand a chance against Neiro. No, I have no idea why I click on the mana shiled in the middle of the fight - such random actions are common during my first solo adventures in the instances of Outland. As for the endboss, I could have killed him a few levels later, especially after getting Deep Freeze at level 69, but I had no desire to do so, instead focusing on soloing other dungeons.
