The Keratinos Blade and Gauntlet is one of the new weapon components added to Warframe in Heart of Deimos. Those looking to unlock the full Keratinos are meant to sacrifice the Keratinos Blade and Gauntlet as parts in the Foundry to make the actual weapon. Both items can be purchased from Father in the Necralisk on Deimos using standing with the Entrati.
The Keratinos are acquired by reaching the Rank of Neutral with the Entrati. Father sells the main blueprint for 1,000 Standing and component blueprints for 500 Standing; a total of 3,000 Standing is needed for all parts. It’s pretty easy to get this, so it won’t take too much time.
Check the map below to find where Father is located, and head there to get the stuff from him that you need.
There’s a good idea to do with these if you plan to trade them in for Standing you do not need to build the Keratinos Blade and Gauntlet first. You simply need to have the blueprints unlocked for the Standing requirements to be satisfied. You will need to invest the time in getting ranks with the Entrati by trading in Standing Tokens and caught game to earn some easy Standing.
You can also earn Standing by doing Bounties for the faction as well. All the Tokens you collect via Fishing, Mining and other activities can be traded in to Father for plenty of rewards. These Tokens will be needed to continue ranking up with the Necraloid Syndicate as well.
