I've had a lot of problems trying to do this quest. (Forum history indicates others have as well.)
I've only found the Slansin up that looks like the merchant. According to the wiki, this should be the version that only gives positive faction, but when I turn in the potion, he depops and gives the Craftkeepers and Heretics faction.
I logged in today and saw the merchant version again, so I killed him. However, I gained Craftskeepers and Heretics faction and lost High Council/High Guard of Erudin faction which seems odd.
Every time I try to trigger Slansin and receive the potion, Slansin does not trigger. I just have to wait a few hours for Slansin to spawn again.
Can this be looked into, as I'm not sure this quest is functioning how it should be?
It seems that possibly both Slansins might be showing up as a merchant and are on a timer rather than triggerable if not up?
