Crag
Cragmaw Deep is a crag biome that runs up to Threat 25, 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 27 rooms — 1 entry, 17 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 4.17 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 → Scuttler and Imp Overlord → The Mountain Sire.
