Recent lurker making the jump to query.
In my first playthrough of EftP, I immediately decided I wanted Demonslayer.
this leads to me entering Drath's crypt at level 17 for the final piece. Unsurprisingly, my hindquarters are thoroughly kicked, but i get the tip, and read drath's spellbook, gaining the unique skill. After several attempts to kill the boss, I give up, and leave.
A full 10 LEVELS LATER, I am sent back to retrieve the book. This time, I am able to fight Drath, and do so. However, I can not interact with the spellbook at all. Nor is there a dialogue option to abort the quest.
Due to my... somewhat nonlinear exploration, I'm not sure this counts as a bug, but it's obnoxious to not be able to complete this quest.
Any advice/options?
