Is it still possible to do the strategy where you prolong Phase 1 as much as possible, and then try to burn him down from 70% to 0% during Amber Scalpel/Reshape Life casts?
My guild tried it today, and we got him down to 2% and the Monstrosity spawn, we kept DPSing the boss but he would not go below 1 HP.
So my guild is wondering, is it still possible to do this strategy and we just didn't have the DPS or this method of doing the encounter is no longer viable.
