How to Trade Up to MAG-7 | Heat
MAG-7 | Heat drops from Chroma 2 Case, so any contract that can produce it needs 10 Mil-Spec skins from that same case. Here is what the contract costs, what else it can land on, and the input float you need for each exterior.

Buying is cheaper than rolling. A Well-Worn MAG-7 | Heat costs $1.29 outright, against $2.50 for a contract with a 25% chance of producing one. Trade up for the process, not the value.
The contract
10 inputs, all Mil-Spec, all from Chroma 2 Case. Concentrating every input in one case is what keeps your odds at 25% — mixing cases splits the probability across both pools and lowers your chance at MAG-7 | Heat specifically.

|---|---|---|
| AWP | Worm God | 25% | $2.29 |
| CZ75-Auto | Pole Position | 25% | $1.30 |

Input float for each exterior
CS2 normalises float across a trade-up: each input’s float becomes a 0–1 position inside its own range, those are averaged, and the average is applied to MAG-7 | Heat’s range of 0.00–1.00. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | 0.0350 | 0.0350 |
| Minimal Wear | 0.1100 | 0.1100 |
| Field-Tested | 0.2650 | 0.2650 |
| Well-Worn | 0.4150 | 0.4150 |
| Battle-Scarred | 0.7250 | 0.7250 |
“Not reachable” means MAG-7 | Heat’s own float range never enters that exterior band — no combination of inputs can produce it.
What MAG-7 | Heat is worth right now
Worth comparing against the contract cost above before you commit: buying the skin outright is frequently cheaper than rolling for it.
| Exterior | Price | vs. contract cost |
|---|---|---|
| Well-Worn | $1.29 | −$1.21 |
| Battle-Scarred | $1.30 | −$1.20 |
| Field-Tested | $1.35 | −$1.15 |
| Minimal Wear | $2.35 | −$0.15 |
| Factory New | $8.22 | +$5.72 |
