Blizzard have announced that the stacking nerf to enemy health and damage in the Dragon Soul raid will be starting next week. It will increase in 5% increments every 2 weeks until it reaches its 30% catp.
Starting next Tuesday, March 18, with the weekly content reset, all enemies in Dragon Soul will be affected by the “Presence of the Dragon Soul” aura, reducing their health and damage by 5%.
Every two weeks thereafter, this health and damage reduction will increase by an additional 5%, culminating in a total 30% reduction by the end of May.
If players wish for an extra challenge and want to fight the enemies of the Dragon Soul raid without the aid of this aura, they may speak to Lord Devrestrasz inside the raid at the entrance and request that he remove it.
