Since an unlisted change removed Conclave Score from every equipment and mod.
Each Tenno's mod collection has an overall rating, which is visible in the upper-right corner of the Mod Collection screen.
Mod Capacity functions as a limit to what mods can be equipped depending on their drain.
Mods can have a drain of 0 to as high as 20 depending on the mod and what rank it is.
Types of mods with special characteristics are listed below: Aura Mods are Warframe mods that benefit the entire Cell and also increase the player's Warframe total mod capacity.
They can only be equipped in the dedicated Aura slot and only one Aura can be equipped to a Warframe.
The amount of mod slots an item will have depends on what type it is: increased their mod drain to 11, up from 9, builds who had those mods equipped and had 0 remaining mod capacity will show a negative capacity, such as -1 as it flashes red.
Mods can grant Passive Powers, Active Powers, Sentinel Precepts, and Utilities. There are around 842 mods existing in the game excluding Riven Mods.
Items also have a minimum mod capacity, which adds mod points onto items which are a lower rank than a players current Mastery Rank.
