How to Trade Up to Tec-9 | Avalanche
Tec-9 | Avalanche drops from Revolver 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 Tec-9 | Avalanche costs $1.08 outright, against $1.90 for a contract with a 16.67% chance of producing one. Trade up for the process, not the value.
The contract
10 inputs, all Mil-Spec, all from Revolver Case. Concentrating every input in one case is what keeps your odds at 16.67% — mixing cases splits the probability across both pools and lowers your chance at Tec-9 | Avalanche specifically.

What else this contract can land on
A contract from Revolver Case draws uniformly from every Restricted Pistol skin in the pool, so Tec-9 | Avalanche is one of 6 equally likely results. These are the other 5.

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 Tec-9 | Avalanche’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 Tec-9 | Avalanche’s own float range never enters that exterior band — no combination of inputs can produce it.
What Tec-9 | Avalanche 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 | $1.08 | −$0.82 |
| Battle-Scarred | $1.09 | −$0.81 |
| Field-Tested | $1.70 | −$0.20 |
| Minimal Wear | $3.80 | +$1.90 |
| Factory New | $10.19 | +$8.29 |
