Step by step: how to complete
Poison harvest disaster quest *Spoiler warning*
- Talk to Hugh, get the harvest disaster quest.
- Go to the cave west of Blue Boar inn.
- Kill the orc inside the cave, take the key he dropped.
- Report to Hugh.
- Go to the BB inn cellar, in the room full of poison (orc's key unlocks the door).
- Speak with Splinter, the barman. He'll tell you that room was rented by Elrath.
- Report to Hugh.
- Go to the poor quarters and watch the cut-scene with Elrath.
- Go to Elrath's house in Rivertown market and speak with Elrath. He'll tell you the key was stolen.
- Report to Hugh.
- Go to Elrath's house again (key is south of his house, use alt key to see it).
- In Elrath's house, click on the lanterns and get to the cellar.
- [color:"yellow"]Drag & drop the letter (in the cellar on table) to your inventory and take two cure potions.[/color]
- Speak with commander Ralph in Rivertown watch and show him the letter.
- Report to Hugh to finish the quest.
Two cures from the Elrath's cellar are potions 3 plague victims in the quarantine want.
Since there are 2 potions and 3 victims, when you cure one victim you can pickpocket or kill him/her to get the cure back.
Killing cured victim wont cost you reputation and you'll finish the quest.
Or cheat to duplicate one cure. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
