Good news, Tenno. The Avia Prime Armor is currently up for grabs as part of the Twitch Prime Warframe Loot offering, which means that as long as you are a Twitch Prime member, you can get the armor for free.
If you are already a Twitch Prime member and have linked your Twitch account to your Warframe account, all you need to do is head to the Twitch Prime loot page and hit on the Claim button above the Avia Prime armor. Make sure you grab any other free loot that you may have missed while you are there.
For everyone else, you will need to go through the process of connecting your Warframe and Twitch accounts so you can take advantage of the offer.
- Go to https://www.warframe.com/user and log into your Warframe account
- Click Link your Twitch Account and follow the instructions to link your Warframe account to your Twitch Account
- Log into Warframe and receive your items
You will only need to link your account once. If you are already linked and logged in, you will need to relog to receive your items.
If you are unsure if the link worked, you can check in the Account Management section of your Warframe account. Under user information, at the very bottom, it will tell you if your profile is linked with any Twitch account. If you have an old account there that you no longer use, just hit Unlink, then link your new account instead.
