Archon Mods

Archon Mods are alternative versions of Warframe Mods. They have higher maximum drain than their original counterparts but with stats equivalent to their primed counterpart (if any), and possess unique effects related to Warframe abilities. They are classified as Legendary mods, and thus their rank-up Credit and Endo costs follow other Legendary mods. They're sold by Chipper in exchange for  Stock.
