How phases work

Every Doppler has a paint seed (pattern index) chosen at random when the item is created. The seed selects which part of the Doppler texture lands on the blade, and that gives the phase: Phases 1–4 mix black with red, pink, blue and purple; Ruby is all red, Sapphire all blue and Black Pearl deep purple-black with a pearl sheen. A trade up contract that returns a Survival Knife | Doppler rolls the phase at random, so the cheapest contracts below have the same chance of every phase. Paste an inspect link into the float checker to read the paint seed of any item.

How to get the Survival Knife | Doppler from a trade up

Put 5 Covert skins from one of the cases that contain this knife (Fever Case) into a trade up contract. The contract returns a random knife or glove finish from that case’s pool, so the chance of this exact finish is 3.57% per contract with inputs from the Fever Case (pool of 28); StatTrak™ inputs give the StatTrak™ version. The float of the result is 0.00 + average input float × 0.08.
