During maintenance next week, the Dragon Soul buff/nerf will climb to 20%. This shouldn't be too much of a surprise
for anyone, since we've known all along it'll continue to increase. And personally, I'm looking forward to it. My guild has some new DPSers running with us, and this will be just the boost we need to get heroic Ultraxion down.
Remember that if you want to run without the buff, you can always turn it off by talking to Lord Afrasastrasz at the beginning of the raid.
Blizzard's full announcement is as follows:
At the completion of scheduled server maintenance during the week of April 30, the "Power of the Aspects" spell will grow more powerful, reducing the health and damage dealt of all enemies in the Dragon Soul raid by 20%. This spell will grow progressively stronger over time to reduce the difficulty and make the encounters more accessible. The spell will affect both normal and Heroic difficulties, but it will not affect the Raid Finder difficulty.
Don't need the help of the Dragon Aspects? The spell can be disabled by talking to Lord Afrasastrasz at the beginning of Dragon Soul.
We hope you continue to enjoy Dragon Soul, and that these changes encourage you to attempt a higher difficulty, or just keep pushing to down that next boss.
