Similar to the existing quests around the Necromentate and perhaps sharing the same NPCs... I would like to suggest a new quest along the same lines, but with a specific effect.
- Can be completed once per game month.
- Once complete, anyone that TOUCHes it (or some other interaction) gets an immunity to the Dionamus curse.
- Immunity lasts until the end of the game month.
Maybe even have it last a bit longer if the quest isn't particularly easy...
