I always liked Path of Exile more for planning a build than for running maps, so I made a game that is only that part. You don't control the fight. You carve rules into trigger runes, things like "every 6 seconds, cast Meteor Strike" or "when hit, cast Blizzard", send your character into a trial and watch. Then you take the loot back to the workshop, craft the affixes you want, socket links into your skills and try again. There are no levels or classes. All the power comes from gear.
The fun I'm going for is the moment the runes fire the way you pictured, and the moment a craft finally rolls what you wanted.

The demo does not save progress. Saves and the leaderboard are in the free full version, linked from the game page.
Graphics are plain shapes for now, and I used AI tools during development. I would like to hear where it got confusing or where you stopped playing.
