So my party is in the second part of the second book. Going into the necropolis. I kind of messed up. I let the cleric have a spell that breaks the story line. Corpse compass. This spell as I read it. lets them use a part of an undead to find its maker. My dilemma is do I let them skip straight to the end of part 2, or do I/Can I reason away to make the spell fail. Anybody else encounter this problem how did you handle it? How would you handle it?
