Buffs
Keep up Blue Betty, Ice Fortress and Lotus Flower. Be sure to apply Elemental Drain to any boss.
Rotation
Start with Backbar DOTs: Blockade Of Frost and Winter’s Revenge. Bar Swap:
Then: Sated Fury -> Deep Fissure -> Fetcher Infection -> Heavy Attack -> Deep Fissure -> Heavy Attack -> Bar Swap
Then: Recast Blockade and Winter’s Revenge -> Bar Swap -> Deep Fissure -> Fetcher Infection -> Heavy Attack -> Deep Fissure -> Heavy Attack -> Bar Swap
Notes
Rebuff after the above rotation. Turn off Sated Fury as needed once the health loss is too strong to heal. For example, you may want to turn off Sated before you rebuff.
