and no matter how good the healer is they will not have a chance to keep the player alive. Once the effect ends start back in on the boss.
Keep adjusting to his abilities until you manage to kill him. The fight has a few more effects than most heroic bosses, The Pit of Saron. There is an instance portal at the end of the room that will take you to the Pit so that you do not have to run all the way back to the beginning to get out.
,This fight requires that everyone watch what is going on and be ready. The fight starts with the tank establishing threat against the Devourer of Souls and then DPS starting on him. Players should spread out so that any time Wailing Soul is cast or Well of Souls is cast cheapest wow gold it will only hit a single player at worst. Each time he jumps to a player to cast Well of Souls the tank moves him back away from the well so DPS has a clear area around him.
You then just need to watch for his special abilities. When he casts Unleashed Souls players should group up and healers can AOE heal to affect everyone and just wait them out while focusing on the boss.
When he casts Wailing Souls you will see the breath effect and he will slowly sweep through a 90 degree arc. This is very similar to the Mimiron fight in Ulduar. Just avoid it and get behind him.
The worst of his abilities is Mirrored Soul which is cast quite often, Jaina or Sylvanas will speak to you again and ask wow gold for sale you to meet her in the next instance, or at least it seems like wow buy gold it. As soon as you see it then all DPS must stop and wait until it expires. A well geared group will kill the affected player in no time flat if they keep DPSing, and feels more like a raid fight. If you are not used to raid fights just give it a chance and keep trying even if you wipe a few times. Once you down him and understand the mechanics it is a very fun fight.
