Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Grimsorrow Academy is large and systemic: fifteen Disciplines, a full combat layer, prestige, and an endgame that descends for hundreds of hours. It is close to completion and stable to play now, but a game this interconnected only truly balances against real save files. Early Access helps us polish and balance the game. ”

Approximately how long will this game be in Early Access?

“Around three months. The game is content-complete from first scry to endgame, so Early Access is about tuning balance and pacing against real players and opening the last gated depths. ”

How is the full version planned to differ from the Early Access version?

“The 1.0 version opens the two depths currently gated for Early Access: the Cave and Hellplore. It adds new content on top of them: further zones, Disciplines, familiars and deeds, alongside the balance and quality-of-life changes that come out of Early Access feedback. Saves are intended to carry forward, so nothing you earn in Early Access is lost at 1.0.”

What is the current state of the Early Access version?

“Fully playable, start to endgame. The mirror, all fifteen Disciplines, Night Errands with its loot system and Anvil, the Black Covenant prestige, Tenure and the Undercroft, honest offline progression, five save slots, a full settings suite and a synthesized score are all in and stable.”

Will the game be priced differently during and after Early Access?

“Yes. Early Access carries a lower price as a thank-you to early players. The price will increase when the game leaves Early Access at 1.0.”

How are you planning on involving the Community in your development process?

“Development is driven by how people actually play. We read and post in the Steam Discussions on this page, run a Discord for real-time feedback and balance talk, and fold what we learn into regular updates”

About This Game

You signed the indenture. The page was still warm.

Grimsorrow Academy is an idle RPG of dark academia and spellcasting dread - two games in one save, narrated by a clerk who has read your file and found you wanting. Scry a black mirror for the dark itself. Attend fifteen forbidden Disciplines. Every ten years, sign again for more power. The school never lets you graduate. It only lets you go deeper.
Scry the mirrorScry the Obsidian Mirror to unlock your Disciplines and advance through the school year. Spells can be cast to move faster, but the ledger balances, and everything is paid for.



Draw your spells
Spells are not bought. They are learned and trained by hand. Trace a spell's mark on the glass to cast it: instant Maledictions, sustained Litanies, and Bindings that scry in your place. Only the strongest learn to cheat their own examinations and idle them.



Attend your Disciplines
Discover the fields of study: gravebotany, cryptmining, blackforging, hexweaving, and more. Master each action for permanent perks; craft the gear and potions that see you through the Night Errands. Bank enough Attunement and the darkest crafts of the Academy open to you.



Work the Night Errands
After curfew, the Professors keep a list, and the lists have teeth. Fight across 23 zones, 12 dungeons and over 90 monsters. Harness their unique drops and sets, then take them to the Anvil that reforges gear +N until it sings (or shatters).



Sign the Black Covenant
When the umbra runs deep enough, sign a new Indenture. It shatters the mirror and voids your contract - and pays you for both: Seals that bless every life after this one, and Oaths spent down a permanent tree. You keep the power. You keep signing.



It only goes down
Earn Tenure and raise your ceiling across 120 levels. A second realm opens beneath the Winding Stair: the Undercroft; and below that the Maw; and below that, what the lore will not decipher. All stairs here go down.

What waits in the school

  • 8 umbra Sources · 12 draw-to-cast spells · 68 unique mirror upgrades

  • 15 Disciplines with per-action mastery, gear, potions and permanent Sigils

  • Idle combat: over 90 monsters, 23 zones, 12 dungeons

  • A 16-node prestige tree, a 300+ deed ledger, and a four-quadrant completion journey

  • Honest offline progress, with a Welcome Back report

In Early Access, the school is already complete and stable, playable from first scry to endgame. The deepest doors - the Cave and Hellplore are closed across Early Access.

Do not feed the staircase.
