Finally brought my Soothsayer (just Spirit pets) up there and defeated Typhon (first try) even though it took 40 minutes and 6 pauses of the game so I could rest. It was quite annoying and tedious and he dropped absolutely nothing useful, not one green.
One of the main reasons for the annoyance has to be this instant kill of my Outsider. It is level 3 (1300 health?) it would run over and about a second later it was dead. The timer felt like a day up there and I only used it 4 times (kept hoping it would do something) but it would just walk up and die. I had Heart of Oak on so I thought that would have helped.
The lich fared slightly better but he felt compelled to stand under each meteor attack.
This is probably the worst character ever to face him with a whopping 255 in dps with some bleeding and energy, life-leech from the staff, 1600health and no resistance over 45. So if she can do it, anyone can! Combined armor was 130! Attack speed 93%. Drank 70 potions, had 5 left when he fell.
