Aura

Auras are a type of Mod that provides a passive beneficial effect to Warframe(s) during a mission. Unlike Mods, Auras will affect the entire squad rather than the Warframe it is equipped on exclusively. If several players in a cell carry copies of the same Aura, the Aura's effects will stack.

Your aura will benefit you individually and then your entire team as a whole. What this means is you get the effect of certain Auras twice such as or any Amp Aura for example. This is why is written the way it is.

Additionally, Auras add to your total mod capacity rather than deduct from it like regular mods. Furthermore, equipping an Aura in an aura slot of the same polarity further increases mod capacity by double the Aura's drain (e.g. an Aura with a drain of 5 generates an additional mod capacity of 10). In a slot without a polarity, the capacity is the same as the listed drain, and in a slot of a different polarity, the additional capacity is 80% of listed drain, rounded down (e.g. a drain of 5 generates a capacity of 4, a drain of 9 generates a capacity of 7, and so on).

The Aura slot can be polarized with a to fit the user's needs.

Acquisition
Primarily, Auras are obtained as Alert mission rewards. Some Auras can be obtained after completing The Silver Grove quest.

Trivia

 * Aura Mod cards were converted from user's Artifacts as of, including additional copies if the user obtained more than one artifact before the update.
 * For a short time after, some Auras (as well as some mods) could have been acquired via transmutation. This was due to a bug where all mods (including the unreleased ones) became obtainable through transmutation. This has been fixed, though some Auras (such as ) have since been released. The list of retrieved auras can be found in Category: Retrieved Content.
 * Sometimes if a game is lagging, the aura effect may not occur or be delayed.

Tips

 * has the highest base increase to base capacity, making it an excellent mod for new frames or frames gaining affinity for new equipment.
