Note: Runes for Fire Wave and a magic weapon are needed for this section and Prayer boosting gear is strongly recommended. * Head back to the previous room. * Talk to the Dying knight near the doorway on the East wall. * Turn on Piety (optional to avoid constant damage and stat reduction) and enter the East room. * Take the five stone slabs from around the room and use them to build a bridge across the central pool. * Cross the bridge and use fire wave on the explosive barrels. * Return to the previous room.
