During Curse of Arrav, the tunnels have experienced some recent cave-ins, and the rubble must be cleared, requiring level 64 Mining, in order to navigate them. Larger pieces of rubble must be cleared from multiple sides. Tablets detailing Lamistard's experience while digging the tunnels can be found in four stone types: granite, shale, slate, and stone. The tunnels can be used to access Zemouregal's fort.
