ToF gives you a 20% damage and healing increase when you damage/heal someone below 20% health which would give you a decent dps increase considering all of the adds/orbs/walls you kill consistently throughout the fight.
Mindbender would just be used to help get down the fourth set of orbs more consistently during phase two.
Thoughts? Is mind bender comparable to (name escapes me, but the ability that procs mind blast)? Would twist of fate be comparable to the mind spike talent on this fight?
