Tainted Blood

This Thirian task requires you to contaminate the blood supply in the Temple of the Maiden Desmodus. This is the first Thirian task where you will face Johannasburg's amazing soldiers, the Blood Knights. If one sees you, it will automatically attack you, dealing massive damage and breaking something or causing an affliction. You probly will want to steer clear of these as they are very strong. If you do fight some, you can be enemied from Johannasburg if you're caught, so be careful. After getting this task, go to Bleek. From the crossroad, go southwest, west, and south to get to Brady, the butcher. Greet him and SAYTO YILK. He'll drop a jug full of Yilk. Grab it, and head to Grasspointe. From there, head into the forest south of Grasspointe. Enter through the southwestern gate of Johannasburg that leads into the Temple district. Make sure you don't go to the Market district gate. Most likely you will have to open the gates. Open the first gate, go east, and open the next gate and go east again. From here, go 2 east, and 2 north. Greet the begrieved mourner here, then head into the MAUSOLEUM. Go down, 3 east, up, east, north, and northwest. Here drop the jug of yilk. After that, return to the taskmaster the same way you came and get your reward.
