Recall Knowledge DC 18 (arcana)
Disable DC 18 thievery (trained) to carefully trigger the collapse without entering the tunnel or DC 22 thievery (trained) to brace the tunnel so it is safe to pass through.
A tunnel through this steep barricade is rigged to collapse. If a kobold spends one action to throw a lever, the tunnel collapses on the next creature to pass through.
