Crippling Gra'al Shul

Steps
I need to enter the Gra'al Shul Temple to the northeast and taint the alchemy lab that is being used to coerce the nudfin fishmen. I also need to kill some of the Gra'al Shul alchemists.

The entrance is guarded by 2 Venril adherents (70) and just further in are 2 Gra'al Shul guards (72), all of whom see invis!


 * 1) Taint the alchemy lab and kill some Gra'al Shul alchemists
 * 2) * Kill 3 Gra'al Shul alchemists
 * 3) * Right-click on one of the alchemy stations and "Taint" it (This does NOT break invis!)
 * 4) Return to Hroar
