In area W12, there is the Stygian Fires trap that is triggered by opening the door on one side. It's bypassed by lighting the fires and donating blood. My question is, where do the PCs need to search in order to detect the trap? The door? The altars? Either?
Obviously this is one that could easily be ruled differently by different GMs, but just curious what others have done.
I ended up letting them notice it at the door. Makes sense since the door is the trigger. But just curious how others would have ruled.
