How it plays
In The Iron Colossus, you create a character with a point-buy stat spread, then trade blows with the AI dungeon master through stat-modified dice rolls. The AI dungeon master (GPT-4o, with Gemini 2.5 Flash as a fast fallback) narrates each scene, reacts to your typed or spoken actions, and calls for dice rolls when the outcome is uncertain.
Your inventory, gold, health, and 15 equipment slots update automatically from the narrative — pick up a sword in chapter one and the AI remembers you have it in chapter four. Food, rest, potions, and healing magic each affect survival in distinct ways, and difficulty adapts to how aggressively you play. In hardcore mode death is permanent; in standard mode you can rejoin the story through the Resurrection system.
