Inaros is an Ancient Egypt-themed Warframe, generally considered the most difficult to kill Warframe in the game, with the correct construction. The Inaros dodges shields, relying on his substantial health bar and ability to generate armor to keep him alive.
Inaros can only be obtained by completing the Sands of Inaros quest, which is purchased from Baro Ki’Teer for 100 Ducats and 50,000 Credits. The quest can be obtained from Baro while he’s in the Relay, so it’s available every two weeks. However, you will need to be at Mastery Rank 5 to purchase it.

During the Sands of Inaros quest, you will need to assist Baro Ki’Teer in a personal matter. You can start the quest from the Codex. This is a very interesting quest that gives an in-depth look at Baro’s history. Much of it is spent charging up an old ship, killing certain types of enemies, and the quest ends with a boss fight that doesn’t happen anywhere else in the game. Don’t forget to scan the boss when you have the opportunity because you will not have another.

During the quest, you will get the main blueprint of Inaros, as well as blueprints for his chassis, neuroptics, and systems. You can then build the components in the Foundry and combine them with the main blueprint to build the Warframe itself.
