Astrea is a DICE-deck-building roguelike that flips the script on deckbuilders by using dice instead of cards and an unique dual “damage” system: Purification vs Corruption. Features • Unique dual “damage” system: Purification vs Corruption - In Astrea there is a new type of “damage” system. Purification can be used to damage enemies or heal yourself. On the other hand, corruption can be used to damage yourself or heal the enemies. Pacify enemies through Purification, or Corrupt yourself to unleash abilities that help tip the scales. • Dynamic Health Bar system - With skills attached to your health bar, you can take Corruption to enable these skills and unleash powerful abilities. But be careful, if you take too much Corruption you will be consumed by it. • Not cards, but dice! - Build a dice pool that fits your playstyle. Choose from over 350 dice and three dice types; reliably safe, perfectly balanced, or powerfully risky. A dice type system designed with high-risk, high-reward in its core. • Customize your dice - Forge your fate by editing die faces with new actions, tipping the odds of powerful results into your favor. • Choose from Six Brave Oracles - Each possessing their own unique dice sets, abilities, and playstyles. From ingenious spellcasters to brutish berserkers, whether you like beating the opponent into submission or outsmarting them with clever plays, there’s an oracle for you. • Uncover over 170 modifying Blessings - Imbue your Oracle with unique passives yielding potent effects that changes up your fundamental tactics. Choose between Star Blessings, passive effects with lower power, or Black Hole Blessings, powerful passive effects with a drawback.
