Transition:
Demon Portal: Then BoP on tank who teleport then use Skytep ‘s potion and full clean a line
Raid pack on one point for healing then when clean is done use portal then a Roar / Wind’s totem.
2Nd Platform:
I have see a strat than all raid except the 2 ppl target by the beam are pack on a point aside the boss, then move other side of the boss when Mines are coming. Then the raid is going other boss’s side and the off tank cleaning the mine.
So boss do not need to move.
