Cards come in three types:
| Keyword | Description |
|---|---|
| Exhaust | Permanently removed after use (gone from your deck for the fight) |
| Innate | Always appears in your opening hand at the start of each combat |
| Retain | Stays in your hand at the end of your turn instead of being discarded |
| Permanent +N | Damage increases permanently each time you play it (stacks across the run) |
You can upgrade cards at the smithy in a Rest Site. Upgraded cards gain a "+" after their name and improved stats. Double upgrade (++) enhances the card even further, indicated by a gold border.
Combat is turn-based. Each turn you receive 3 Energy and play cards that cost Energy to use.
