Your father is Grim, the Grim Reaper. To bring Isabella back from the dead, you must hunt monsters, tear power from their souls, and build a deck strong enough to defeat him.

Grimslair is a dark fantasy roguelike deckbuilder set in a hand-painted world that changes every run and grows deadlier each night.

CREATE CARDS THAT SHOULD NOT EXIST

Blank Battle Cards let you build new cards from scratch. Soulwords ripped from fallen enemies reshape your cards with new damage, targeting, resource gains, status effects, and dangerous tradeoffs. Cards also level up as you use them, so the deck you start with is never the deck you finish with.

BREAK GRIM'S CHAINS

Grim deals enemy cards onto a five-slot chain. Connected cards can unleash multiple attacks and effects in a single turn. Play cards to charge your Chain Breaker, then shatter a connection before the full chain activates.

EXPLORE, BARGAIN, OR KILL

Every run rearranges its paths, locations, enemies, and rewards. Cross graveyards, forests, caves, deserts, and frozen mountains as the clock races toward nightfall. Choose a safer route or risk deeper territory for greater rewards.

Trade with strange vendors or kill them and take everything. Give souls to Grim for perks or keep them to unlock more Soulwords. When a choice goes wrong, Time Warp cards let you turn back the clock.

FIGHT BESIDE YOUR DOG

Your husky fights with its own cards, abilities, and upgrades. Build its deck, strengthen its attacks, and turn your companion into a lethal part of your strategy. Yes, you can pet your dog!
