Chain builder

What a chain is A chain is several contracts in a row inside one collection: the outcome of one goes straight into the next, and no fee is paid on intermediates. Choose which rarity to start from and how far to go — even from Consumer to a knife. The craft list only keeps popular chains; here any can be calculated.

Calculate your own chain

I already have intermediate items Enter their float and the site will count how much to buy

Items of the same collection at any intermediate rarity work. An own item one step higher replaces ten bought ones a step lower, two steps higher — a hundred. The average f′ of the bought items must then be such that the outcomes stay the same.

Pick a collection and press «Calculate».
