-When you start the fight, player 1 will use he's channeling spell (Number 3 on pet par) this is a 10sec cast.
-When you see player 1 have started channeling player 2,3,4 and 5 will start attacking with the normal ability, (Number 1 on pet bar)
-When player 1 reaches 10 stacks on he's channeling, player 2,3,4 and 5 will start channeling.
-When player 2,3,4 and 5 have started channeling player 1 will use a Time Stop (Number 2 on pet bar)
-After player 1 have used Time Stop, player 1 will start attacking with he's normal ability until player 2,3,4 and 5 have 10 stacks on their channeling.
-When player 2,3,4 and 5 got 10 stacks they start attacking with normal ability again, exept from player 2.
-Player 2 will use a Time Stop before he start attacking.
-player 1 starts channeling again (this must happen right before player 2,3,4 and 5 starts attack again!)
-Now player 1 will channel until 10 stacks then the boss will most likely go into a "void" where he become immune.
-What you must do here is run avay from the "orbs" in the air, if you get hit, its most likely a wipe. As you dont have a healer ofc.
-After this very easy phase, All start over again!.
-Expet this time player 1 and 2 dont have Time Stop. So when the boss can be attacked again player 3 will use a Time Stop before attacking, Then player 4, and 5 if needed.
Then just repeat all i have explained above.
If you get adds before the first immune phase its a wipe, adds before the 2nd immune phase is acceptable, but its hard. If you get adds before the first immune phase try put a third Time Stop before the boss goes immune and maybe you wont get adds.
