ICC Tactics for the Lady Deathwhisper boss.

Please correct me if i am wrong about something.

Lady Deathwhisper

very much simular to Kel'thuzad

Lady deathwhisper will start in a mana shield that need to be dpsed down. the mana shield will go off when the boss mana is gone.

on the right side 3 adds will spawn often. and the middle add should be tanked. and the other 2 adds next to the middle add should be dpsed at first and then go for the middle add.

on the left side 3 adds will spawn and tank should just go pick em up and dps'ers should aoe them down.
There are sertin targets for ranged dps and melee dps. some of the adds is immune to physical dmg and some are immune to spell dmg.
so melee on the target that is immune to spells
ranged on the target that is immune to physical dmg.

as in Kel'thuzad players will gett Mind controlled and Mages should sheep them asap. or shaman do hex.

the new thing here is that. Lady Deathwhisper will stack a debuff (max 5) that will lower the tanks treath by 20% each stacks.
i dont know if she is tauntable then. but the other tank should be gaining up threath above hes treath and should aggro the boss.
so the tank should stop dps at 2 stacks and the other tank should dps as hell. its about to have about same threath both tanks.
that is on heroic mode ofc, on normal mode she is tauntable. so start taunting on about 2 stacks so no dps will overaggro.

and boom shes dead.
Important: the spider add before boss will make a spell on a target that does a aoe and drain life from all partymembers near the afflicted target so run 10 yards from youre partymembers and stay there untill the explotion comes. dont go out of range from healers.

The adds will be resurrected. Some of them will be immune to magic, some to melee
