What Refined & Flawless Aetherium Crystals Are Used For
With the release of Black Ops Cold War Season 2, Treyarch is adding a bunch of new content into the Zombies section of the game.

How to Get Refined Aetherium Crystals in Cold War Zombies
To get Refined Aetherium Crystals, you’ll want to play the new Outbreak Zombies mode. The developers have suggested that completing multiple objectives will eventually lead to players earning some of these crystals.
Refined Aetherium Crystals will also be awarded to players in traditional-round based zombies modes beginning in Season 2. You must reach Wave/ Round 20 to be rewarded with a Refined Aetherium Crystals, instead of the normal Aetherium Crystals.
You’ll then earn another Refined crystal every five levels.
How to Get Flawless Aetherium Crystals in Cold War Zombies
As for Flawless Aetherium Crystals, you’ll also want to play the Outbreak Zombies mode, and push through numerous objectives.
You’ll likely have to push through even more rounds than you do for the Refined Aetherium Crystals, though at this moment it remains unclear just how many objectives you need to complete before they’re awarded.
Flawless Aetherium Crystals can also be earned in traditional round-based zombies modes in Season 2 as well. You’ll have to reach at least Wave/ Round 35 to be awarded a Flawless Aetherium Crystal. These are then awarded every five levels.
