A Flawless Aetherium Crystal can be obtained by completing the Two Factor Authentication Mission in Call of Duty: Modern Warfare 3 (MW3) Zombies mode. Read on to learn how to get Flawless Aetherium Crystals and the Flawless Aetherium Crystal Schematic!
List of Contents
Greylorm is a hidden boss in MW3 Zombies that can only be fought inside the Aether Storm after the match time ends. To fight this boss, you will need to collect 4 Calibration Data USBs and place them in the Refractor terminals inside the Aether Storm.
After you kill Greylorm, a Reward Rift will spawn that has a chance to contain a Flawless Aetherium Crystal Schematic, a Scorcher Schematic, or a Legendary Aether Tool Schematic.
Do note that these are not guaranteed drops. You will likely need to beat this boss multiple times to get all possible Schematic drops from it.
| Where to Find Flawless Aetherium Crystal |
|---|
| 1. Completing High Threat Contracts (Repeatable; Low drop rate) 2. Complete Two Factor Authentication Mission (Only once) |
You can get a Flawless Aetherium Crystal in Reward Rifts from completing Contracts in the High Threat Zone.
Take note that the rewards from these rifts are completely random, so you may have to do a few High Threat Zone contracts before you'll be able to stumble onto a Flawless Aetherium Crystal.
Completing the Two Factor Authentication Mission will reward you with a Flawless Aetherium Crystal. You can get this mission once you reach Tier 1 of Act 3.
Zombies Acts and Mission Rewards
Consuming a Flawless Aetherium Crystal lets you upgrade the weapon you're currently holding to Pack-a-Punch Level 3. This lets you save up 15,000 Essence and skips the long process of having to farm up for all those Essence.
