Consumed in the fusion process to power up existing Mods. A single Legendary Core will instantly fuse a Mod to its maximum capacity without credit cost.
—In-Game Description

  • Can be traded with other players (with a base tax of Credits64 1,000,000 per Core).

Notes[]

  • When trading, Legendary Cores are found in the Mods section.
    • Outside of a trade one can check how many Legendary Cores they have by opening their Mods collection (default: Esc  > EQUIPMENT > MODS) and selecting any single mod (below maximum rank) for fusion and the clicking on START FUSING INTO SELECTED MOD. The number of Cores will be displayed in top right corner of the game window above LEGENDARY CORE label.
  • The most efficient use of a Legendary Core is on rank 0 Primed, Umbra Mods or Archon Mods, such as Mod TT 20px Primed Continuity, Mod TT 20px Umbral Fiber or Mod TT 20px Archon Intensify, which would save 40,920 Endo Endo and 1.7m Credits Credits. The second-most efficient use of a Legendary Core is on rank 0 Rare Mods that have a maximum rank of 10 (including Galvanized mods), such as Mod TT 20px Blind Rage or Mod TT 20px Galvanized Scope or Mod TT 20px Amalgam Serration, which would save 30,690 Endo and 1.4m Credits, relative to 75% savings compared to the Primed/Umbra/Archon mods.

Trivia[]

  • Legendary Core is currently the only item in game that appears in Trading listing selection, but does not appear in any inventory listing selection (including Mod listing selection).
  • Legendary Core has two different context-dependent icons: one in Trading window and another in Mod window (but is not the only item with this feature - since Credits Credits and many common Resources also have multiple icons).
  • Before Update: The Silver Grove (2016-08-19) was deployed:
    • Legendary Core was stored in the form of a mod card, before converted into a Fusion resource.
    • Legendary Core was the first Legendary-tier mod ever distributed in the game. The next being primed mods offered by Baro Ki'Teer and Daily Tribute.
    • Legendary Core was the second mod with no fusion levels after Mod TT 20px Coolant Leak.
    • Legendary Core was the only mod that does not provide any mod value in the Mod storage total value.
  • Originally given out during Update 12.2 (2014-02-19) to all players who possessed a Mod TT 20px Steel Charge Aura mod that was rank 6 or higher as a compensation for the resources players have spent in ranking up Steel Charge, as the subsequent update changed the mod's rank from 10 to 5.

Patch History[]

Hotfix 37.0.2 (2024-10-03)

  • Removed the controller binding that applies a Legendary Core to a mod during Fusion to prevent players from accidentally selecting it.
    • Now, if you wish to apply a Legendary Core you can manually do so by moving the virtual cursor over the button and selecting. If you accidentally did this since the launch of Koumei & the Five Fates, you can submit a ticket to support.warframe.com.

Hotfix 37.0.1 (2024-10-02)

  • Improved the Fusion confirmation popup to make it much more obvious that you are using a Legendary Core.
    • This is so that you don’t accidentally consume those precious Legendary Cores unintentionally! If you have since the launch of Koumei & the Five Fates, you can submit a ticket to support.warframe.com.

Hotfix 36.0.2 (2024-06-19)

  • Fixed a crash caused by Legendary Core.

Update 18.0 (2015-12-03)

  • Added as a Sortie reward.

Hotfix 17.9.2 (2015-10-30)

  • Legendary Cores have been distributed to all players that have had the Affinity Amp Aura removed from their inventory.

Hotfix 17.4.1 (2015-09-10)

  • Fixed players being able to transmute Legendary Fusion Cores.

Hotfix 12.2.1 (2014-02-20)

  • Fixed Legendary Cores not fusing Mods to maximum level in some situations.
  • Fixed Legendary Cores being consumed by Auto Fusion.

Update 12.2 (2014-02-19)

Introduced
  • After a lot of observation and discussion, we realized we have to change the Steel Charge Aura back to a maximum of 5 ranks. The additional mod capacity set a new precedent and was just too much. At 10 ranks, Steel Charge allowed for some fun new builds, but it also meant that the additional slots would always have to be considered when balancing other mods and Auras.

The damage bonus from Steel Charge is not a problem and is very much intended, so the damage bonus at 5 ranks will be changed so that it as similar to the bonus at 10 ranks.
As compensation to all of you who worked hard to rank up a Steel Charge, anyone who has a Steel Charge above rank 5 will receive two Legendary Cores, the first of their kind. These Legendary Cores instantly max any mod with 0 credit cost.

Summary:
  • Maximum rank reduced to 5 (down from 10)
  • Melee damage bonus remains similar.
  • Players who have a rank 6, 7, 8, 9, or 10 Steel Charge will receive 2 Legendary Cores.

Last updated: Hotfix 25.7.5 (2019-09-09)
