Argon Crystals in Warframe are a very rare resource that works a little differently to most resources in the game. It is the only resource in the game that can disappear from your inventory because of decay. If you farm up Argon Crystals, unused crystals still in your inventory will halve every 24 hours. So if you farm 8 of them, and use 2, you will then have 6 left. These six crystals will be stable until midnight UTC, but will then start to decay. The next time the clock hits midnight UTC, you will only have three crystals left. The time this decay occurs is set to midnight UTC, so always keep this in mind. You should only farm the Argon Crystals that you need, then use them straight away. This means you won’t need to worry about the decay clock at all.
Warframe – How To Get Argon Crystals
Argon Crystals can be found in missions in the Void. They can drop from enemies, containers, or from large Argon deposits that can sometimes be found in the levels. They are a very rare drop, so you need to do some farming to get them.
Argon Crystals are affected by abilities like Desecrate from Nekros, Pilfering Swarm from Hydroid, and other abilities that cause a reroll of a dead enemy’s loot table. Ivara can also use Prowl to steal Argon Crystals from enemies.
It is advised to run a squad featuring a Nekros, Pilfering Swarm Hydroid, Trinity, and a Loki in a Survival mission. Find a spot on the map with one entrance and camp there with Pilerfering Swarm in the doorway. As the enemies flood the room they are caught in the Swarm and killed, then the Nekros can reroll the loot. The Trinity keeps everyone healthy and the Loki can use stealth to go out and keep life support topped up without disrupting the flow of enemies. You can net anywhere from 8-16 Argon Crystals every 30 minutes using this method.
To solo farm these crystals, missions like Exterminate and Capture are the best, as they provide a large map to search, and plenty of enemies to kill. Drops will also be affected by Boosters, and the Smeeta Kavat’s Charm ability, increase your haul.
Corrupted Vor, who can appear in Void missions, can also drop an Argon Crystal upon death, so be sure to kill him if he shows up. While there are some other ways to get Argon Crystals, the Void missions are considered the best way, as you can run them quickly, especially with a group, and gather up any crystals that they contain.
The last important thing to keep in mind about this resource is that it is not refunded to you if a cancel a build in the Foundry, so always make sure you are building the item you need when it comes to Argon Crystals.
