No, I’m afraid we do not provide refunds for a bugged quest. Here is the general refund policy.
I don’t know the status of this one, but I do know that our QA and Dev Teams are aware of it.
Once a resolution is found it usually depends a fix is usually applied with a Hotfix or may require a patch. It really depends on what needs to be done to resolve the issue. A lot of things can be resolved with a hotfix, but not everything and adding it to a patch takes a bit more time.
Sorry for the frustration, Krelorllan.
Edit: I do see a note indicating that at higher levels (around 40) Farondis seems to survive better. I don’t know if that is an option for you, but thought I’d mention it.
