How to Trade Up to P2000 | Obsidian
P2000 | Obsidian drops from Shattered Web 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.

The contract
10 inputs, all Mil-Spec, all from Shattered Web Case. Concentrating every input in one case is what keeps your odds at 20% — mixing cases splits the probability across both pools and lowers your chance at P2000 | Obsidian specifically.

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 P2000 | Obsidian’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 P2000 | Obsidian’s own float range never enters that exterior band — no combination of inputs can produce it.
What P2000 | Obsidian 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.
