Grimm Forge

About the Game

Dark Fantasy Roguelike Deckbuilder

What Is Grimm Forge?

Grimm Forge is a free-to-play roguelike deckbuilder set in the world of R.J. Stenson's debut novel. You play as a Grimm, a dragon-blooded warrior reborn in the forge fires, delving into the miasma-choked depths of an ancient dungeon, building a deck from four disciplines, and deciding when to extract before the corruption claims you.

The Core Fantasy

Build. Delve. Extract. Or Die.

Every run begins with a choice: which Grimm do you send into the depths? Each one carries a starting deck built from one of four disciplines (Combat, Flame, Stone, or Storm) and the cards you find inside will shape everything that follows.

The deeper you go, the richer the rewards. But the miasma rises with every floor, and death in the depths is permanent. Only what you carry in your secure pouch survives the journey back.

Extraction beacons offer a way out before the darkness takes you. The question is always the same: do you push deeper for one more reward, or do you cut your losses and live to fight again?

Deckbuilding

Choose your discipline. Draft cards from the dungeon. Build a deck that survives the deep floors.

Extraction

Use beacons to escape with your loot. Push too far and lose everything. Timing is survival.

Permadeath

Die in the miasma and your run ends. Only your secure pouch survives. Every decision matters.

Progression

Your guild persists between runs. Unlock new cards, relics, and upgrades that carry forward.

What Sets It Apart

More Than a Deckbuilder

Extraction Mechanics

Unlike traditional roguelikes where you fight to the end, Grimm Forge rewards smart exits. Every run is a risk-management puzzle. Carry too much and you might lose it all. Extract too early and you leave power on the table.

Lore-First World

Every card, enemy, relic, and event is rooted in the mythology of The Grimm Forge novel. The miasma, the disciplines, the forge fires... it all connects to a larger story that the book tells in full.

No Forced Class

Your Grimm is not locked into a single discipline. Start with Combat and unlock Flame as you level. Mix disciplines to create builds that no one has tried before. Every Grimm is built different.

The Four Starting Disciplines

Choose Your Path

Combat Grimm discipline
Combat

Strike hard. Defend harder. Master of weapons, armor, and raw physical power.

Flame Grimm discipline
Flame

Burn everything. Fire damage, AoE devastation, and the Burning status.

Stone Grimm discipline
Stone

Unbreakable defense. Shields, thorns, and endurance that outlasts anything.

Storm Grimm discipline
Storm

Speed and chain lightning. Draw cards, gain energy, strike from everywhere.

More disciplines unlock as your Grimm levels up. No two builds are the same.
