It was soo much fun and very intense. If you have not tried it I totally recommend it. Lots of helpful tips from other players in the comments below if you are looking to solo it also. (Edit) Thanks to everyone who added helpful tips for other players who wanted to try this! Also, thanks to everyone else for your, highly entertaining, riddles and comical questions <3 Ninja ((Edit)) Strategy I used: lvl 29 Warlock sunsinger, with The supremacy arc sniper and Steel Oracle arc rocket. When cracking the door I hung back near the entrance of the room and slowly cleared the waves ,on the last wave when the wizards spawn I ran back up the stairs and picked them off as they followed. When facing Phogoth I ran a circle around only stopping long enough to shoot him. Ignore the adds and more will not spawn. Downed him 3-5 minutes. Take your time, don't rush and play it safe.
