You can re enter the passage by using a trapdoor by the rock face near the first goblin tribe on the left when you exit the village that takes you back into the secret passage from the chapel. Im in the citadel dungeon and i cant find the skill book mentioned in the guide i only get 4 weapons and a cage come down but the cage is empty can some help please.
Yes, you can re-enter the passage from near Broken Valley, but
not from the chapel side, which might keep you from getting some things in that section
if the cave-in was triggered.
In the citadel dungeon, after lowering the four weapons, face away from the door leading out and walk until the room opens up to the left. In the corner is a skill book on a chain.
