Once her mana shield is gone, the boss becomes attackable and stops calling addsInstead, she casts "Frostbolt", which does 30,000 damage and must be interrupted, continues to cast Death and Decay, and casts "Touch of Insignificance" on the tankThe Frostbolts can easily be dealt with by two interrupters switching off, or a Shaman with Wind Shear cooldown improved.

Touch of Insignificance is a stacking debuff which reduces threat generated by 20% each time it is applied, up to 100%For this reason, two tanks are needed in this phase and should switch every three stacks to avoid having the DPS overtake them in threat and gain aggroThe debuff lasts 30 seconds.

Deathwhisper also summons "vengeful shades" to pursue players, which are blue ghostsThe targeted player simply needs to run away from the group until the shade disappears, as it will do AoE damage if it reaches the player.
