Flawed Mods (previously called Damaged Mods) are weaker versions of preexisting Mods initially intended for newer players, originally obtainable during the Vor's Prize quest. They are identified by visible cracks on the mods' image as well as the word "FLAWED" in their descriptions.

As of Update 34.0 (2023-10-18), Flawed Mods were intended to be antiqued, with all Flawed Mods being converted to non-flawed variants (with the exception of the April Fools Mod TT 20px Flawed Ammo Drum). These antiques can now be purchased from the mod storage box near Cressa Tal at Iron Wake.


Prior to Update 34.0 (2023-10-18), Flawed Mods were awarded while progressing the Vor's Prize Quest. Flawed Mods only dropped during the questline missions, with the exception of the Mercury Junction which rewards flawed copies of Mod TT 20px Fast Deflection and Mod TT 20px Streamline. From Hotfix 18.6.2 (2016-03-22) onwards, these mods cannot be traded. Following Update 34.0 (2023-10-18), they are sold from the mod storage box near Cressa Tal in Iron Wake for Credits64 10,000 for common rarity, Credits64 20,000 for uncommon, and Credits64 30,000 for rare.

Flawed Mods still provide the same effects as their normal counterparts. However, as their name suggests, these mods have reduced power and/or rank. Flawed Mods come in three types:

  1. Reduced base capacity drain, reduced effect, and a maximum rank of 3.
  2. Reduced effect, and a maximum rank of 3, with base capacity drain unchanged.
  3. A maximum rank of 3, with base capacity drain and effect unchanged.

As a rule, most mods have only one flawed counterpart, selected from the pool of flawed variants above. For example, the mod Mod TT 20px Serration has a flawed mod with reduced drain, effect, and maximum rank, and no other flawed variants.

There is no way to "unflaw" a flawed mod.

These mods effectively gave new players a hand when starting out, as normal mods may be too costly to rank up (both in terms of Credits and Endo), or too capacity hungry, especially without any Orokin Reactors or Orokin Catalysts to increase mod capacity on new players' equipment. Once players start gathering enough supplies and mods, they were free to convert these mods to Credits/Endo to strengthen their normal counterparts or keep them, with the first type still being useful for some loadouts due to a reduced capacity drain, thus being able to fit where a non-flawed mod would not fit. They can also be transmuted.

List of Flawed Mods[]

Flawed mods with reduced base capacity drain and reduced base effect are shown 1. Those with unchanged base capacity drain and reduced base effect are shown 2. Those with unchanged base capacity drain and base effect are shown 3.


  • When it comes to installing mods on your equipment, Flawed Mods are considered identical to their normal counterparts and cannot be equipped simultaneously.
  • Flawed Mods do not count towards the Codex entries of their respective normal mods.
  • Flawed Mods cannot be obtained through Transmutation, even if all the mods used are flawed themselves
  • Flawed Ammo Drum was available as a reward for a 1-hour Survival mission on April Fools 2016. This was the only way to obtain Flawed Ammo Drum, and it was the only Flawed Mod that did not drop from Vor's Prize or a Junction. As of Update 34.0, it is the only Flawed Mod that cannot be purchased at Iron Wake.


Patch History[]

Hotfix 34.0.1 (2023-10-18)

  • Fixed the Flawed Antitoxin Mod being 10k Platinum instead of 10k Credits in the Steel Meridian Surplus.
    • For those who flexed and spent the downpayment’s amount of Platinum on the Antitoxin Mod, a script has already been run to refund it!
  • Fixed the Acrobat, Marathon, and Quick Rest Stamina Mods appearing in the Steel Meridian Surplus. Stamina is a relic of the past and serves no function in modern day Warframe.

Update 34.0 (2023-10-18)

Removal of Flawed Mods from Vor’s Prize

Flawed Mods
Flawed Mods are a special variant of Mods that are only accessible via the Vor’s Prize Quest and were intended to be an early introduction for players to the Modding system. Over the years, we have come to understand that these Mods have the unintended effect of players investing Endo that would be better used in the non-flawed variants.

As a result, we have removed Flawed Mods from Vor’s Prize and replaced them with the normal variants. Additionally, players who already own Flawed Mods have had them replaced with the normal variant with this update's release -- excluding the April Fool’s Flawed Ammo Drum from 2016, of course. The conversion maintained the Mod rank, so a Rank 3 Flawed Vitality has become a Rank 3 Vitality, etc.

Any equipped Flawed Mods have been uninstalled, so be sure to check your builds if this affects you!

Flawed Mod Storage Site
After posting our initial Dev Workshop outlining the Flawed Mods removal, many players expressed their desire to keep them for a variety of reasons. Luckily for those Tenno, we managed to find the original (disposal) storage site of the Flawed Mods and have made them available to players once more.

Seek out the storage site near Cressa Tel in Iron Wake on Earth to purchase them anew. We did our best to price these rare finds fairly, keeping in mind that these are now collector’s items of course, so they can be yours for the cost of a few (thousand) Credits!

While this is a tongue-in-cheek implementation of new Flawed Mods acquisition, we appreciate the value that these Mods offer to certain players and wanted to keep them available for those who requested it.

Note: Due to the unique acquisition method for these Mods, players will not be able to dissolve Flawed Mods for Endo or Transmute them.
