Grimslair

Achievements
In Grimslair you step into the role of Adam, son of the Grim Reaper, drafted into the family business under a brutal deal: reap enough souls each day and Grim will keep listening to your plea to bring your girlfriend back to life. Survive 15 days, but if you miss the quota or die, the clock snaps back in time... deck refreshed, ready to go for another run. Collect and fuse Soulwords that change how your cards behave: more damage, new targeting patterns, resource gains, status effects, and powerful tradeoffs. Evolve favorite cards across loops and experiment with builds that only work because you’ve bent the deck into something uniquely yours.
