I used a barbarian with Max snake, gladiator other epic passives with endgame poison gear. Got lucky and found an relic with timewave. Had other proccs with timestrike such as belt, body armor and that charm cfs . Time wave leeched life/mana. At the end i could do fauzt in 2 mins with no life loss. 350k psn dmg at timewave , 180- psn res. When playing with relic i could easily Max out snake bite with 690k dmg. Good bossing and farming!
