Two layers of money
Hades splits progress into run money and home money. One resets when you die; the other stays and compounds across attempts.
Confusing the two is how players hoard the wrong thing. Spend the temporary pile; bank the permanent one.
Run currency
The currency you carry in a run buys boons, health, and shop items. It disappears when the attempt ends.
Spend it on what the current room demands. Holding it for a shop that never comes is a lost run.
Home currency
The currency you bring home upgrades the House and unlocks weapons, keepsakes, and traits. It compounds every attempt.
Sink it into broad unlocks first. A new weapon or keepsake helps more than a thin stat bump.
