Lady Deathwhisper Boss Strategy Guide
Your tanks automatically become extra DPS players for this encounter due to Mana Shield. Split your party into two groups: ranged DPS and melee DPS. Ranged DPS should focus on Lady Deathwhisper, while melee DPS will run around the room and take care of the many adds she spawns constantly.
Lady Deathwhisper spawns a new round of adds every 60 seconds, on alternating sides of the room, so melee DPS should clean up one side before heading over to the other side to work on the next set. All physical damage melee DPS should focus on the adherents, while magic damage melee takes out the fanatics. Watch out for the adds to explode from time to time, dealing a lot of damage.
Lady Deathwhisper periodically casts Death and Decay on a party member. It shows up as a huge green circle on the floor. Make sure you run out of it as soon as it’s cast to avoid the damage from it.
If you’re playing in the 25-player mode, Lady Deathwhisper will take over control of one (or three in heroic mode) of your party members at any given time. Use your crowd control tactics on any players under the spell of Dominate Mind.
Phase two of the battle against Lady Deathwhisper begins after you’ve knocked down her Mana Shield. Tanks head back into a traditional tanking role. They’ll need to use all powers to hold aggro on Lady Deathwhisper at this point because of her ability Touch of Insignificance.
Party members who can interrupt spellcasting should keep interrupting her Frostbolts because they do a lot of damage.
Lady Deathwhisper’s adds during phase two are ghosts which chase party members and kill them, so avoid them completely. Just run away when one gets near you.
