Primes may be the ultimate goal in Warframe, but not all of them are easy to obtain. Some of the best Warframes and weapons in the game are locked behind Prime Resurgence, and you’ll have to put in some extra work to unlock them.
Every Warframe Isn't Locked!? (Prime Resurgence Event Guide)
Prime Resurgence is a rotating vault of items that you can use if you happen to have some very special currencies available. We'll show you how to get those currencies and where to pick up your Prime goodies.
Prime Resurgence is a monthly rotator in Warframe that grants players access to content in the Prime Vault. The Prime Vault is where a selection of Prime Warframes and weapons are stored, and everything in the Vault is not accessible through the usual Void Relic system. Instead of the usual reward for these relics, players can obtain a resource called an Aya.
Aya can then be traded to an NPC named Varzia in Maroo's Bazaar on Mars in exchange for certain items, including the Relics that contain the Vaulted Prime parts. There is also another resource called Regal Aya that can be purchased for real money if you want to skip farming altogether or purchase something like a cosmetic that can't be purchased with standard Aya.
