Banking refers to the mechanic wherein the player saves the Rings they have collected during gameplay, storing them separately on a different account from their Ring count for later use in order to purchase different upgrades. This occurs automatically when the playable characters enter a Junction. As the Rings are banked, the player can seen how many Rings they have currently stored on the HUD. Also, each time the player banks their Rings, their Ring count is multiplied by an increasing number, starting with a 1 × multiplier up to 5 ×.
While banking prevents the player's Ring savings from being lost when taking damage, the process renders the player ringless, leaving them vulnerable to harm.
