Biomes/Bloodspire Keep

Bloodspire Keep is a keep biome that runs up to Threat 20, and everything in it is Blood — so Bleed and the Exsanguinate payoff are the language of the fight. The Vampire Lord waits at the end, with 960 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: ImpGorespittle Pup and Imp OverlordThe Vampire Lord.
