*Use Purge on first boss to dispell poison from totem.
*On last boss we experimented with combinations of using Echoing Vigor/Bone Surge/Circle of Protection. We found simply having the extra hot from Vigor was more beneficial and sustain-friendly.
*Reasoning behind Enchanted Forest Ulti is for last boss we had the OT & Arcanist healer alternate barriers through torturer frenzy phase, warden healer used Forest effectively on CD since it is a cheap, strong heal, this kept a huge amount of healing up on the group to make the last floor manageable.
