Astrea: Six-Sided Oracles (PC) GOG Key Global

Not cards, but dice! 

Astrea is a DICE-deck-building roguelike that uses dice instead of cards and has a unique dual "damage" system: Purification vs Corruption. Create a dice pool powerful enough to cleanse Astrea's rampant corruption and save the Star System.

A one-of-a-kind dual "damage" system: Purification vs. Corruption - There is a new type of "damage" mechanism in Astrea. Purification can be utilized to either harm or heal your opponents. Corruption, on the other hand, can be utilized to harm yourself or cure your foes. Purify your enemies or Corrupt yourself to unleash skills that help tip the scales. Dynamic Health Bar System - By attaching skills to your health bar, you can take Corruption to empower these skills and unleash incredible abilities. However, if you drink too much Corruption, you will be consumed by it.
