 * Coalesced Corruption (8)

Description
My clairvoyance provides a great strategic asset to the people of Ramkahen. However, the potency of my visions of late has proven taxing to my health.

I have devised a tonic that may serve to dull the harm these visions cause, but it will require the coalesced essence of the Old Gods' corruption.

If you could retrieve some samples of this for me, it could prove invaluable in our efforts.
