The pact is sealed. Your life is the price. Alchemy is your only escape.
You dreamed of mastery — of unlocking the ancient secrets of the Philosopher’s Stone. Desperate for power, you struck a bargain with a Homunculus: a demon that grants you knowledge beyond measure… in exchange for your life force. Every step of the way, your “partner” grows stronger — and you fade weaker. Your only hope? Outsmart it. Craft the legendary Stone. Break the pact before it consumes you.
This is the gripping premise of Corpus et Spiritus — the all-new alchemy roguelite deckbuilder from Arpentor Studio and Firesquid, live on Steam right now.
How you play — no swords, just wits
Unlike most deckbuilders, there are no monsters to slay and no enemies to battle directly. Your only opponent is the pact itself — and the cunning entity feeding on you.
- Gather rare metals — collect resources across runs, each with unique properties
- Craft in your workshop — transmute metals into cards and talismans. What you put in shapes what you get out
- Seven card families — Body, Mind, and Soul branches offer distinct playstyles to master
- Balance three vital resources — Health, Wits, and Stamina. Let any drop too low, and the Homunculus claims you
- Negotiate with the demon — trade life force for powerful boons, or refuse and face its wrath. Every run begins with a custom pact you design yourself
- Discover the Philosopher’s Stone — piece together the ultimate recipe through experimentation, then use it to sever your bond and survive
