Fever Collection trade-ups in CS2: four live Fever Case contracts with float bands in the write-up. Cost, expected value, and profit update live on each card from the Trade-Up Database.

Fever skins drop from the Fever Case. Ten matching inputs trade into one skin of the next rarity inside the Fever pool. Every card below deep-links into the Trade-Up Calculator so you can recheck floats, fees, and outcome prices before you buy.

For other ladders, see Train 2025, Sport & Field, Gallery, Ascent, Kilowatt, Souvenir trade-ups, and knife trade-ups.

Selection rules for this post

  1. Screened at publish for positive live expected profit and fully priced outcomes
  2. Optimal float span at least 0.03 when markets allow
  3. Distinct rarity and wear bands across the picks
  4. Input asks stay tight across marketplaces (2nd-cheapest within ~15% of cheapest, and still profitable if you clear at that 2nd ask)
  5. The article lists skins, float bands, and pool notes only
  6. Live cards show current cost, EV, and profit, and open in the Trade-Up Calculator

4 picks at a glance

  1. Zeus x27 | Tosai (Factory New), optimal float 0.0000 to 0.0487
  2. Desert Eagle | Serpent Strike (Field-Tested), optimal float 0.1500 to 0.2157
  3. P90 | Wave Breaker (Battle-Scarred), optimal float 0.4500 to 0.9505
  4. Nova | Rising Sun (Well-Worn), optimal float 0.3800 to 0.4500

How Fever Collection trade-ups work

  1. Add 10 skins of the same rarity from the Fever Collection (or a valid mix with other collections if you intentionally split odds).
  2. Collection odds follow the share of each input.
  3. Output float follows the average float of your ten inputs and the outcome float range.
  4. Buy inside the printed optimal float range, set your sell fee, then confirm EV on the live card or in the Trade-Up Calculator.

How to run the contract

  1. Confirm cost, expected value, and expected profit after your fee on the live card.
  2. Stay inside the optimal float range. Wider spans leave more room when listings move.
  3. Use Open in Calculator on the card when you want to swap one filler or reprice the contract.
  4. Recheck prices right before you commit. Case-collection books still move with supply and listing depth.

FAQ

Can you trade up Fever Collection skins in CS2?

Yes. Ten skins of one rarity return one skin of the next rarity from the Fever outcome pool, the same rule as other weapon collections.

How do you pick these Fever trade-ups?

Picks were screened for fully priced outcomes, a usable float band, positive live expected profit, and tight input listings across marketplaces so the contract does not depend on one cheap listing. Distinct rarity and wear bands keep the list useful. Always recheck the live card.

Where do I see live cost, EV, and profit?

On each live trade-up card below, or by opening the same recipe in the Trade-Up Calculator. This article does not freeze dollar costs or profit percents in the prose because those move with the market.

Is Fever a case collection?

Yes. Fever skins drop from the Fever Case. Once finishes are tradable and marketable, they work like any other collection ladder in a trade-up contract.

Where else should I look?

Trade-Up Calculator, Trade-Up Database, Train 2025 Collection trade-ups, Sport & Field Collection trade-ups, Gallery Collection trade-ups, Ascent Collection trade-ups, Kilowatt Collection trade-ups, Souvenir trade-ups, and CS2 knife trade-ups.

Keep checking live prices

Fever books shift with case supply and marketplace depth. Re-open each card before you buy, set the fee for where you sell, and stay inside the float band. Build or tweak any of these crafts in the Trade-Up Calculator, or browse more contracts in the Trade-Up Database.
