Set Mods

Set Mods are a unique class of Mods that offer increasing bonuses when one or more mods in a set are equipped on the player's Warframe and weapons.

Each Set consists of 6 Mods at most, with individual mods providing standard stat increases and bonuses, but also providing a second Set Bonus stat that is shared between all the mods in the set. Set Bonuses are improved through the number of mods in the Set equipped - the more mods in the set are used, the stronger the Set Bonus.

Set Bonus effects are not improved by upgrading the mod through regular fusion. Only the number of equipped mods within the set dictates the Set Bonus strength.

They are first introduced in Update 22.0 (2017-10-12) with the Augur, Gladiator, and Vigilante sets.

Notes

The Augur Set can replenish shields even after life support has run out in a survival mission.
The Vigilante Set's "Enhance Critical Hits" bonus refers to the ability to upgrade the Critical Damage level of the weapon by one rank, i.e. if the weapon deals a "yellow" critical, there is a 30% chance that it will deal an "orange" critical instead, dealing more critical damage. Another way to think of this is X% chance for +100% additive crit chance.
The ability to get set bonuses with even a single mod from a set should not be overlooked. This allows players to take the best mods from each set to further optimize their builds.
Hunter Companion mods cannot be used on sentinels.
While Set Mods can be equipped on Exalted Weapons, they will not contribute to nor benefit from set bonuses, but the regular effect of the mod will still apply. This also applies to Venari.
