Icecrown Citadel 10m: Heroic Lady Deathwhisper - Overview/Phase One

The Heroic mode for Lady Deathwhisper is extremely simple and the general setup of the raid and encounter goes mostly unchanged. In this guide I will only cover what is important and anything else you should honestly know if you're doing Heroic modes. Depending on the class, gear, and players' abilities you'll want 2-3 healers, 2 tanks, and the rest dps. As for the positioning, have healers stand in the center so they can reach everyone and range between the boss and side adds for phase one.

• This is one of the easier Heroic modes for 10m and poses a bit of a challenge for 25m but, is very doable for any guild who has downed the Lich King. The main changes are a doubled health pool for Lady Deathwhisper, increased damage from Lady Deathwhisper, other abilities, and Vengeful Spirits as well as a shortened enrage timer. Also adds will still spawn during phase two and raiders can be MC'd throughout the fight in both phases.
• Phase one is extremely simple, short, and just like normal except raiders can be MC'd and overall damage taken is increased. Range DPS focus down adds and position yourselves between the boss and adds for easy switching. Healers be sure to keep everyone's health pools high, Melee watch for cleave as you can be almost one-shotted, and Range nuked kited mobs quickly. Also make sure to immediately kill Reanimate, Empowered, and Deformed mobs.

Icecrown Citadel 10m: Lady Whisper - Phase Two & Recap

• Once the mana shield is down you'll enter phase two. In Heroic, Lady Deathwhisper's health is doubled so this phase will last a lot longer than normal. You should pop Blood Lust or Heroism towards the beginning when aggro is usually more stable or whenever your tanks feel comfortable. The main tank will want to pick up the boss and kite her towards the beginning of the room near the stairs. Here the offtank and main tank will switch off picking up adds. The adds are nothing to worry too much about and are easily killed but aggro on Lady Deathwhisper during this phase can be a serious problem. Make sure Rogues are tricks'ing and Hunters are MD'ing the tanks on switches. Call out for Salv if need be. Players still get MC'd during this phase so make sure to CC them quickly. Finally, take Vengeful Spirits more seriously by running away from them and make sure everyone is spread out since they now blow up in a 20 yard radius.
• Do all that and you'll down her with ease.
• Just to simplify and recap heroic key points.

Phase One:
Balance DPS on boss and adds
Immediately kill Reanimate, Empowered, and Deformed mobs
Melee avoid Fanatic's cleave and Deformed mobs
Don't stand in Death and Decay

Phase Two:
Watch tanks' debuff
Watch aggro carefully
Nuke adds
Interrupt frostbolts
Run away from Vengeful spirits
and most importantly, have fun!
