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 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 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.
