Indicated by a scales icon on the minimap. Can deposit or withdraw coins. Coin balance persists between runs and is the same across all characters and difficulty levels. Banks have a coin deposit limit of 10 per room with no withdrawal limits. Entering the bank with a balance of 100 coins or more allows the player to "collect interest" in the form of a secret bank chest.
Indicated by a skull icon on the minimap. Contains the boss and the portal to the next area. Guaranteed to spawn.
Indicated by a crossed swords icon on the minimap. Has a lever that can be used up to 3 times to spawn enemy waves of increasing difficulty. When each wave is defeated, a chest will spawn.
Boss challenge room
Indicated by an icon of two crossed swords behind a helmet. Has a lever that can be used once to spawn a miniboss. When defeated, a challenge chest will spawn.
Indicated by a magic sparkle icon on the minimap. Contains an equipment item from each of the 4 types (head, armor, hands, feet) on pedestals. Upon selecting one, the other 3 will lower into bottomless pits and cannot be picked up even if the player gets to them fast enough. The pits will deal damage if the player jumps in after the items.
Indicated by a quadruple diamond icon on the minimap. Contains an altar where you can use 30 coin to permanently lock the effect of current items (For the current run, not further runs). This allows you to wear up to 8 items on you. Prestiging more than once is possible if another room is found, allowing more items to be worn. It is not possible to activate an item that has been prestiged. Barter does not affect the price.
Indicated by a golden treasure chest icon on the minimap. Contains a locked Golden Chest. Sometimes has an extra locked chest behind a barrier that deals 12.5 damage when walked through (in both directions, so 25 damage total to get in and out). Guaranteed to spawn.
Indicated by 3 circles on the minimap. This room is rare and has four portals leading to different levels, being Asgard, Vanaheim, Svartalfheim, and Helheim.
Indicated by a banner icon on the minimap. Sells equipment, healing and stat boosts. One room variant has a secret shrine. Guaranteed to spawn on every floor. The shop contains 2 pedestals at the start, but can go up to 7. Spending coins increases Huginn's Loyalty Card and unlocks more pedestals. Has the following inventory:
- Two middle pedestals: unlocked by default.
- Two left pedestals: unlocked at 10 and 100[verification needed • edit • ?] loyalty.
- Two right pedestals: unlocked at 250 and 500 loyalty.
- Front pedestal: unlocked at 1000 loyalty.
Indicated by a book icon on the minimap. Contains an Ultimate ability book or secondary ability scroll. The item can be seen through the window of the door before opening, allowing players with a keen eye to attempt to identify it. Requires a key to open.
Indicated by an anvil icon on the minimap, and marked with "Blacksmith" above the door. Sells weapons, and later some stat items. Spending coins increases Muninn's Gratitude and unlocks the front pedestals. Guaranteed to spawn once per zone. If you receive a blacksmith on Asgard 1, your next blacksmith will spawn on either Vanaheim 1 or 2, etc. Has the following fixed inventory:
- Center pedestal: Random tier 1 weapon for 5. Unlocked by default.
- Right pedestal: Random tier 1-2 weapon for 15. Unlocked at 10 gratitude.
- Left pedestal: Random tier 1-3 weapon for 30. Unlocked at 100 gratitude.
However, if the current run is running out of weapon pool, higher-tier weapons can appear on lower-tier pedestals, eventually not selling any weapons at all upon emptying the pool. This can easily happen when you generate lots of Weapon Chests using Sigyn's Help.
- Left pedestal: Clip Up for 5. Unlocked at 50[verification needed • edit • ?] gratitude.
- Right pedestal: Damage Up for 5. Unlocked at 250 gratitude.
- Front pedestal: Equal chance of Clip Up or Damage Up for 5. Unlocked at 1000 gratitude.
