Volunteer Work

Volunteer Work is a dungeon & raids achievement earned for defeating Jedoga Shadowseeker in Ahn'kahet on Heroic difficulty without killing any Twilight Volunteers.

Strategy
The original strategy in this fight was to kill the Twilight Volunteers before they reached the center summoning circle to prevent Jedoga from getting a buff to increase her damage by 200%. It would be possible to achieve this if the tank was geared enough to have high mitigation and health as well as the healer being capable of canceling out the damage fast enough.

If you are in a high caliber group, you may only have to put up with one or two stages of her buff and kill her quickly.

Use Disarm and Dismantle to lower damage on tank.
