Summoner: Hellbound Grimoire

· Play · Test report

A neon-fantasy action game for the browser, inspired by the summoner from Hell Mode. You play Allen, a summoner who barely fights himself: your power is the grimoire, a growing army of 100 summon cards across 9 ranks.

No install, no build step. Open index.html in a browser, or serve the folder with any static web server.

Tests

169 automated tests cover every feature: content integrity (all 104 cards, enemies, bosses, 48 stages), Arabic coverage, the Rift, events, skins, automation, online flows (with a fake server), ads, run upgrades, evolutions, Act IV boss phases, co-op, the Village, arena, photo mode, accessibility, install files, saving and migrations, progression, combat (every card and its special skill, every enemy, every boss attack pattern), all game modes, menus, keyboard/controller/touch input, rendering at each graphics quality, and audio. The tests load the real game with temporary storage, so they never touch a real save.

In a browser: open tests/index.html (locally through npm start, or online at https://00-mj-built-with-ai.github.io/26.10-summoner-hellbound/tests/). Add ?only=boss to run a subset.

From the command line (Node 18+; uses your installed Edge or Chrome):

npm install

npm test

npm test -- boss runs only tests whose name contains "boss". The command exits with code 1 if anything fails.
