Paladin Quest likely bugged

[Wern8]

The Paladin only quest that can only been done a single time given by Brother Samael Lashneveous seems to work fine, but the door within is locked and there seems to be no key to open it with, so currently there is no reward at all other than the quest ending's XP.

Though if it is meant to be like this, instead of a bug, then nevermind!

Did you try to open it after killing the boss? I remember having it seen it work.

It worked for me, today.  The door is initially locked.  Upon attemtping to open the locked door, a dialogue window opens.  After selecting the appropriate dialogue choice, the door unlocks and can then be opened.
