Yesterday I drinked in the Chalice of Corruption just for the fun of it. I knew I had to defeat those waves of Afflicted with a 2 health penality and wanted to test my character.
The problem is:
I killed the 3 waves of Afflicted, but still got the quest log message "Defeat the sickened Am Fah". Brother Tosai is still there telling me if I'm ready to see who are my real masters, and the green bursting star is at the same spot from the beginning (in front of Brother Tosai) on my compass. I killed every Afflicted I could in the Undercity, even the ones that did not come in the first waves, but it did nothing.
In short, nothing is happening and no Afflicted are left for me to kill. Is there something else I must do ?
