Altars
Altars are points of interest that can appear within rooms, most of them granting the player some kind of boon when interacted with. The two main kinds are chests and shrines.
Contents
Spawn rules
Altars appear in most normal rooms, excluding the spawn room on each level. One variant of 
Huginn's shop has a secret shrine. Most rooms spawn with a shrine of some kind, but their appearance is not guaranteed.
Once exhausted (which may take multiple inputs), shrines cannot be used again, and will usually glow with a pale fire or a halo to indicate they've been used.
Only one shrine of each type will spawn in a given room, but rooms can spawn with multiple types of shrines.
Shrines, especially secondary rarer shrines, can be located in hard to access places, usually high up on balconies or ledges. While some of these shrines can be reached via creatively jumping from rails, banisters, mushrooms, etc. having a mobility buff like flying, triple jump, super jump, rocket jump, grenade jump, low gravity level modifier or super speed can help. Some shrines may be impossible to reach with the player's current equipment and stats.
Shrines typically behave the same way given their type, but the player's Luck stat can induce other, better outcomes, even from basic shrines.
Summary
Angel and devil altars
Angel Altar
Devil Altar
These altars take the form of large statues with urns, and will accept a random number between 1 and 6 of coins (for the Angel) or keys (for the Devil) in exchange for a random result. The random results include:
- a stat increment consumable, eg.
Luck Up - a
Key (Devil Altar only[verification needed • edit • ?]) - a random equippable item
- an ultimate ability book
- a secondary ability scroll
- a random weapon
- a
Skeleton Key.
Blessing altars
These are the most common altars, and take the form of statues with small offering bowls. They are easily accessible and usually appear along the peripheral walls of the room. They will accept a single coin
in exchange for a +1 boost to the character's stat, dependent on the statue. Often times blessing altars can be difficult to spot; they tend to blend into their surroundings, both in color and in geometry. Scanning the peripheral walls of the room is a good start.

Damocles' sword
This shrine resembles a small pillar with a fiery sword above and one of 3 possible items (listed below). Activating it deals 25 damage to the player, in exchange for whatever is resting on the pillar. The damage can be reduced or avoided with abilities and items like 
Block and 
Valkyrie's Veil, which will negate the damage completely, or 
Skjaldmeyjar's Plate which will reduce the damage to 15. Possible items are:
Coin Bag
Heart Container (rare)- Key.
The Black Market always contains three Damocles' sword shrines: single, double and triple sword shrine each dealing 25, 50 and 75 damage to the player respectively. Possible items are:
- a random equippable item
- a stat up.
Slot machine
These take the form of small, square chests with a slot in the front into which a coin is inserted. Upon inserting a coin a random outcome will occur:
- Nothing. Represented by a puff of smoke.
- An enemy spawns. Can be one of:
- A consumable spawns. Can be one of:
Luck doesn't increases chances to drop Coin Bag and 1
In addition to a previous effect, the machine can jam. The coin will remain in the slot and no further input will be accepted.
Slot machines can be found as a bonus altar in normal room, or in their own special room marked on the map.
The Dish
Located in the right room of Helheim 2. After depositing 100, 
Giant Slayer Boots will appear. All subsequent runs will spawn the boots.
Tribute altar
Is located in special Tribute room, marked on the map, that can only be found in Asgard Crypt. Can accept up to 50 coins one at a time. Each time it accepts a coin, it tries to increase random stat by 1. It may try to increase already maxed stat, which will lead to no practical effect; otherwise, it will increase stat with no side effects.
Prestige altar
Is located in special Prestige room, marked on the map. Will accept 30 coins (paid at once), after which will turn all player's currently equipped items into enchantments, after which they will provide their full effect but without taking a slot. Price appears to be unaffected by number or currently equipped items. (Effect on items that require activation is unknown).
