The Forge of Potential

One roll between 0 and 1 settles it. Below 0.65 the item goes up a level. Above that, the idol's break chance covers the entire remainder, so every failure is a total loss rather than a setback.

The game does carry a gentler third result, where a failed attempt drops the item two levels below the target instead of breaking it. No idol in 1.0 can reach it, because all sixteen set break chance to 1.00 and swallow the whole remainder. If Iron Gate ever tunes one below that, a third row will appear here on its own.

Since patch 1.0.20 the roll isn't fresh. The game seeds it from your character's name, the item and the level you are aiming for, rolls, and saves a new seed for the next attempt with your character. Quitting without saving and loading back in replays the same result, so the reload trick is gone, and each character gets its own fixed run of successes and breaks for every item and level. The Forge predictor shows yours from the character name.

Averaged out, each level past the cap costs about 1.54 attempts, and the wreckage of the failures eats roughly 0.35 extra copies of the item's materials. Refine the thing you would happily rebuild, not the thing you would mourn.

It sits in the Mountains and drops a permanent marker on your map once you get near, the way a trader does. Worldgen reserves 10 sites for it, at least 400 metres apart and never within 200 metres of the world centre. You will only ever get one. The instant a player loads the first site, the game deletes every other reservation, so the forge you walk to is the forge your world has.

Haldor, Hildir and the Bog Witch collapse the same way, which is worth knowing before you plan a route. Our seed map draws every reserved site, because that is what the world generator produces, and the seed finder measures the closest one, which is the one you will actually claim.

Idols come in eight material tiers, split into a battle idol for weapons and tools and a protection idol for armour. The tier has to match the gear, and every one of them rolls the same 65%. Between them they cover 271 craftable items.
