War Paint and decorated-weapon quotes must match both quality and wear. This guide compares Factory New only; select Minimal Wear, Field-Tested, Well-Worn or Battle Scarred in the calculator. Steam USD is recommended because backpack.tf wear-specific coverage is limited. A collection’s output wear follows that collection’s inputs, not another collection’s wear.

How Scream Fortress XIII Collection odds work

With ten Scream Fortress XIII Collection inputs, every next-rarity item shown in the applicable output table has an equal chance. The number of input item names does not change those single-collection odds.

In a mixed contract, each individual input contributes 10% to its collection. Five inputs from this collection therefore assign 50% of the contract to this collection, split evenly among its possible outputs.

Strange and non-Strange items cannot be combined in one contract. Their prices and profitability can differ substantially, so this page calculates them separately.

Market depth, price movement and seller availability are not modeled. Always open the marketplace links and confirm that ten clean, eligible inputs can actually be purchased before trading.
