The same rare pool (same items, same finish set) also drops from Chroma 3 Case, Chroma 2 Case. Covert skins from those cases lead to the same pool in a trade up.

The same knives in a different finish set come from Gamma 2 Case, Gamma Case, Revolver Case.

Chroma Case odds

Valve has disclosed the same rarity odds for every standard weapon case. The Chroma Case follows them:

A knife is therefore roughly a 1-in-385 drop, and each case also needs a key. On average that makes unboxing one of the most expensive ways to get a knife. See CS2 case odds explained.

Chroma Case and knife trade ups

Since the October 2025 update, five Covert skins can be traded up into a knife or pair of gloves. The result is drawn from the rare pool of the case your Covert inputs come from. So five Covert skins from the Chroma Case can only give knives from the list above.

That makes the pool's average value the number that matters: a trade up aimed at the best knife in this case can just as easily land on the cheapest one. Mixing Covert skins from different cases splits your odds between their pools.

More: how the knife trade up works and how the output float is calculated.

Is the Chroma Case worth opening?

Opening any case is a paid random draw: most openings return a Mil-Spec worth far less than the case plus key. If you want a specific knife from this pool, buying it outright is almost always cheaper. If you want any knife from the pool, compare the price of five Covert skins from this case against the pool's average value in the calculator.
