Crag
Cragmaw Deep is a crag biome that runs up to Threat 20, and everything in it is Stone — so Crumble and the Seismic payoff are the language of the fight. The Mountain Sire waits at the end, with 1350 health and 8 Uniques to give up.
A run through it lays out 25 rooms — 1 entry, 15 combat, 2 boss, 2 transit, 1 shrine, 2 branch, 1 loop and 1 placeholder — and draws 0–10 of the combat ones on any given floor. Come in around level 5 for every Threat step you are attempting, with about 12 power for each of your levels.
2 creatures from the shared Demon crowd are swapped out here: Imp → Pebble Scuttler and Imp Overlord → The Mountain Sire.
