There are 2 types of Aetherium Crystals added to Call of Duty: Black Ops Cold War with the release of the Outbreak Mode. These are Refined Aetherium Crystals and Flawless Aetherium Crystals. Both of them can be earned in the regular Zombies Mode and the Outbreak Mode. Players need these items in order to upgrade their gear to Tier 4 and Tier 5. Collecting these materials, however, can be a bit hard. In this guide, we’ve detailed everything there’s to know about getting Refined Aetherium Crystals and Flawless Aetherium Crystals in the Outbreak Mode of Call of Duty: Black Ops Cold War.
Aetherium Crystals in Outbreak Mode
In order to collect Aetherium Crystals in Call of Duty: Black Ops Cold War, players need to progress through the zombies mode. From what we’ve gathered so far, Refined Aetherium Crystal begins to appear after Wave 20 and Flawless Aetherium Crystal appears after Wave 35. After these rounds, players will also get a small amount of Aetherium Crystal after every 5 rounds.
In addition to this, Aetherium Crystal is also awarded for successfully exfiltrating. To sum things up, reach Wave 20 for Refined Aetherium Crystal, Wave 35 for Flawless Aetherium Crystal, and then continue to survive to get even more after every 5 waves.
When it comes to Outbreak, Aetherium Crystals are earned by completing objectives. At the beginning of a match, players will get a series of objectives that they’ll need to complete in order to earn Aetherium Crystals. Once again, players can either continue to complete objectives or simple exfil after getting some.
Remember that Refined Aetherium Crystals start to appear after the third wrap and Flawless Aetherium Crystals appear after the fourth wrap. Another important thing to bear in mind is that all these things stack on top of each other, allowing players to get a lot of Aetherium Crystals in a single run as long as they’re able to handle the increasing difficulty.
Lastly, do note that Raw Aetherium Crystals can only upgrade gear to a max of Level 3. Refined Aetherium Crystals are needed to upgrade a skill to Level 4 and Flawless Aetherium Crystals are required to reach Level 5.
