Curio Key

Bought at the workbench for 100 anima. This key has no destination of its own in this build, so buying it moves the view nowhere and opens no door. The doors table names what opens each door.

The workbench stands in the hub and sells permanent unlocks. Pick one, pay its anima cost and it unlocks at once. Anima is earned by finishing runs. Every entry also carries an ingredient list, but the workbench only checks and spends anima in this build, so those ingredients are never taken from you.

Which keys are on the shelf at all is kept in your save, not on the item, so a key you have not reached yet is simply not offered.
