This fight has 2 phases.
During phase 1 you can't damage Lady Deathwhisper's life, instead, the damage dealt will drain her mana. She also cannot move during this phase.
In 10 man, the side of the room where adds spawn alternates. In 25 man they spawn from both sides, and one random mob from the stairs.
Phase 2 starts when all her mana is drained. The boss can now be moved around the room.
In 25 man HC, Mind Control targets 3 players instead of 1. In 10 man, 1 player gets MC'd instead of 0.
Phase 2: Lady Deathwhisper is not tauntable. Make sure to taunt right before her shield breaks.
Phase 2: Adds keep spawning. 1 from the entrance of the room in 10 man raid + 3 from one side in 25 man raid.
Phase 2: Vengeful Shades now deal heavy damage to all players nearby if they reach their target.

During Phase 1, the boss cannot move and adds will spawn from the sides of the room.
A common strategy is to stand behind the boss and use the healers' natural threat to make the adds come to your raid.
Tanks will have to take aggro on the adds and position them near the boss to cleave them down.
