Room items¶

Room items are the rooms you lay on the board of the Book of the Halls. Any room goes on any map: its biome decides where it drops, the architecture it is built in and the enemies that hold it. Ordinary and boss rooms stack up to 20; unique rooms don't stack.

Place it on the board of the Book of the Halls, by a gate of the halls

Where rooms drop¶

Room items drop like currency from creatures and chests: their family competes with the other currency families by the total weight of the rooms that can drop at that spot, and the rarer the drop, the more it favours boss and unique rooms. A room drops only where its row allows it: in its biome, from a land level on, from elite enemies and bosses, or once a biome's boss has fallen in the world. Creatures inside the halls never drop room items.

Room types¶

	Type	What it holds
	Armory	Weapon racks and weapon rewards, held by its guards
	Treasury	Chests, gold and fitting equipment behind a fight
	Forge	Alloys and materials at its forge once the fight is won
	Ore Hall	Ore veins that open once the hall is cleared (no pickaxe needed to go on)
	Burial Hall	The undead, urns and item racks of the dead
	Cartographer's Hall	Two or three treasure maps in its chests once the fight is won
	Boss Room	An extra boss fight with its own loot. It never gives ascension points: they come only from the final boss

Armory¶

Weapon racks and weapon rewards, held by its guards

Treasury¶

Chests, gold and fitting equipment behind a fight

Forge¶

Alloys and materials at its forge once the fight is won

Ore Hall¶

Ore veins that open once the hall is cleared (no pickaxe needed to go on)

Burial Hall¶

The undead, urns and item racks of the dead

Cartographer's Hall¶

Two or three treasure maps in its chests once the fight is won

Boss Room¶

An extra boss fight with its own loot. It never gives ascension points: they come only from the final boss

In the top cell of the board it is the final boss: ascension points come only from it

In the top cell a boss room holds the map's final boss; on any other cell it is an extra boss fight with its own loot that never gives ascension points. The rooms of the halls' own bosses need no defeated boss: they drop anywhere from their land's level.

Unique rooms¶

Unique rooms have rules of their own. They drop from elite enemies and bosses anywhere from their land's level, are never sold and don't stack.
