Twilight Corruptor

[TeaLeaf]

Raid make up:

Get as many ranged and DOT classes as possible.
Split healers into 3 groups and rotate them so that after an AOE knockback the next group goes out to heal, with 1 regen and the third recovering from the knockback.
DPS uses the healer knockbacks as the prompt to jump out into LOS and refresh DOT or fire off ONE spell only, then jump back out of LOS.  Two spell cast will regularly get you caught in the AOE.
AOE damage is 7-800 every 5 seconds and the debuff lasts 15 seconds.

Pull is made on mount with tank standing just spawn side of the fallen tree.
When pulled into range the MT starts dealing damage which allows the pull to be made beyond the fallen tree.
Two MTs tank the Twilight Corrupter against the side of the ramp (to protect against knockback) and to allow for one being MC'd.
Mages have to keep an eye on MC'd raid members and sheep them ASAP.

Other than this it is a slowish fight lasting about 7 minutes, but fairly straight forward as long as people do not get DPS-greedy and try to stay in LOS to do too much damage.  Remember, for every raid member who dies the Twilight Corruptor gets stronger, so DPS-greedy people can wipe the raid!

Hit him once, get back out of LOS, wait for knockback, repeat.  Result = dead Twilight Corruptor.

He can be re-summoned fairly quickly about 3 minutes after his death by someone with the quest (Sceptre quest line) running in to his spawn point and then out again.
