The Hollow Alchemist

The Hollow Alchemist is a roguelike deckbuilder about Fumiko, a homunculus born without sin who is searching for what it means to be human. Alchemists once tried to create perfect life, but their failures scarred every nation and produced homunculi embodying sins such as pride, wrath and greed. Fumiko travels east with companions who have their own voices, histories and reasons for the journey.

The world and its story

The journey crosses deserts, jungles, ruined kingdoms and holy empires, as well as thirteen nations with distinct histories and cultures. Along the branching route, you encounter quiet villages, war-torn ruins and eccentric homunculi who test you with puzzles. The story follows questions of identity, sin and humanity, with moments that range from light to dark and reflective.

Build and fight

Combat combines cards, elemental reactions, buffs, debuffs and companions. You build decks around Fire, Water, Earth and Wind, or fight without relying on the elements. Dice-based mana makes each turn a mix of strategy and luck, while the elements interact: Water can extinguish Burns, Wind increases Burn, and Earth absorbs Water. Buffs and debuffs can stack in different ways, from steady burns to sudden collapses.

You can create cards of your own by combining the four elements. Companions fight alongside you, and each run brings new choices, cards and story fragments.

The Seven Sins

You face the Seven Sins, and each one you confront leaves a mark. Marks grant power but also change Fumiko, whose use of them allows their voices to creep into her own. The challenge is to survive while deciding what kind of being she will become.
