Fusion Forge: merge three Cromons into one

How the Forge works

1. 1

   Collect three identical Cromons

   Same species, same rarity. Rift mints and the marketplace are your sources.

2. 2

   Confirm the fusion in your wallet

   One transaction on Cronos (10 CRO) burns the three sources and mints the stronger result.

3. 3

   Boosts carry over

   The base Cromon you pick keeps its Cromite levels on the result, and the duplicates' boost value comes back to you.

4. 4

   Field your new fighter

   The forged Cromon lands in your collection, ready for the Arena, raids and the Deeps.

How much does a fused Cromon gain?

Six bonus points placed one at a time on the lowest of its six visible stats, plus one point on each of its two reserved stats, per fusion, all written on-chain by the contract. Every stat is hard-capped at 30, and the visible pool shrinks by one point for each visible stat already at the cap beyond the first, so a Cromon that is nearly maxed gains less than a fresh one. The result is a new token that keeps the species number, the rarity and the element: fusion does not change what a Cromon is, only how strong it is, and it is the only way to raise the on-chain stats after the mint. A Cromon can be fused again with two more duplicates as long as it has room under the cap, which makes a common species you own many copies of the natural first project, and a Legendary you own three of the most valuable one.

What happens to Cromite boosts, and which Cromons can be fed?

The Cromon you keep carries its Cromite boost levels onto the result untouched. The two consumed duplicates give their Cromite back as a budget: it buys the next levels on the result's own boost curve at that curve's prices, and whatever the budget cannot afford is refunded to your inventory as Cromite, so nothing mined into a fuel is lost; the Dojo techniques of the two fuels, on the other hand, do not carry, only the base's do. The Forge only accepts Cromons that are free: one digging in a mine lane, away on an expedition, training at the Dojo, on your Arena defense team, locked in the Gauntlet, exploring the maze or sealed in a Pit descent is shown as busy in its group and has to be recalled first, and a copy listed on the Marketplace sits in the market's escrow, outside your Vault, until you cancel the listing. The fee is 10 CRO, paid in the same transaction that burns all three, the base included, and mints the new Cromon.

Where do the duplicates come from?

Two places. Rifts: a Basic Rift at 20 CRO is 45% Common, so a batch of them piles up the same species quickly, and the species is drawn uniformly among those of the rolled rarity. The Marketplace: when a group is one copy short, a listing of that species and rarity closes the gap, with a 5% buyer fee and no seller commission, and the stats of what you buy are readable before you pay. The Forge screen groups your Vault by species and rarity and shows how many copies you hold and how many are ready, so the shopping list writes itself. Every fusion is an on-chain event: the three burned token ids and the new one are visible on the Cronos block explorer, which is how a fused Cromon proves its history to a buyer later.
