Starting at server maintenance next Tuesday, the Power of the Aspects buff will increase in Dragon Soul. This means that the health and damage output from enemies will be reduced by 10%. Remember that this only applies to normal and heroic versions and that it can always be shut off.
The Power of the Aspects buff currently stands at 5%, which went into effect on Jan. 31, 2011
. So it took about a month for the buff to increase to the next level. Blizzard has said the spell will continue to increase but not at a set interval, as was done in Icecrown Citadel.
The full blue post is as follows:
During the scheduled server maintenance on the week of February 28, 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 10%. 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.
