How to Get The Flawless Aetherium Crystal Schematic in Call of Duty: MW3 Zombies

A Flawless Aetherium Crystal Schematic in Call of Duty: MW3 Zombies allows for Tier-3 Pack-A-Punch weapons always at the ready, so here is how to get it.

Having schematics in MW3 Zombies allows players to prepare for powerful headstarts in their matches. Whether it’s crafting a can of Quick Revive to bring allies back in a flash or bringing in a Ray Gun to strike fear into the undead horde, schematics are vital. The launch of Season 1 for Call of Duty: MW3 brought new schematics to the game’s Zombies mode, including the powerful Flawless Aetherium Crystal. We have provided the intel on acquiring the schematic while playing MW3 Zombies.

How to Get The Flawless Aetherium Crystal Schematic in MW3 Zombies

Players must defeat the Red Worm boss in MW3 Zombies, known as Greylorm, to earn the Flawless Aetherium Crystal Schematic. The process to get Greylorm to spawn is a bit lengthy, but the steps of it will go by quicker than usual. We have highlighted the process to initiate the boss fight below:

  1. Drop into a Zombies match with an entire team.
  2. Scan your map to find two ammo caches that are placed very closely.
  3. Head to the building that looks like an “F” at coordinates H2 on the map.
  4. Look for a room with the map of Urzikstan and enter it.
  5. Four pictures surround the room’s walls and indicate locations to go to.
  6. Mark those locations on your map and head to them.
  7. Comb each of the four areas for items called “Calibration Data USB.” (Four are needed)
  8. Once all four are collected, head to the location in Step 2.
  9. Four devices are in the area. They will activate once the Aether Storm consumes them.
  10. Place the four USBs into the machines, Greylorm will spawn, and the boss fight will begin.
  11. Once Greylorm’s health is depleted, it will be defeated, and players will be rewarded with different items, including the Flawless Aetherium Crystal Schematic.

Players must ensure they extract with the Schematic to unlock the ability to craft the Flawless Aetherium Crystal. If they are downed or do not extract, they risk losing the schematic. As a precaution, make sure to have Tombstone Soda activated, so if you go down, the schematic will be safely stored in your backpack until you spawn in at the next match.

What is the Cooldown on the Flawless Aetherium Crystal Schematic?

Players who use the Flawless Aetherium Crystal Schematic must wait a total of three days or 72 hours to be able to craft one again. It is one of the longest cooldown times for a schematic in Call of Duty: MW3 Zombies. However, it does not count down only in-game and continues to run down in real life. Players should plan carefully when to make use of the schematic.

Schematics in MW3 Zombies have always had cooldowns, with some of the Perk-A-Cola’s in MW3 Zombies only taking a few hours to be usable, while the Wonder Weapon schematics take up to 48 hours to cool down. In using this feature, it is always essential to plan on when you want to use them, so you are not stuck with needing to craft an item but cannot because it is on cooldown.

The Flawless Aeterium Crystal Schematic is a vital schematic to earn, and now that you will be unstoppable after acquiring it, make sure to see what else you can obtain in Call of Duty: MW3 Zombies through our Game Hub, as well as any information concerning Call of Duty: Modern Warfare 3.
