• Riven Disposition (Faint, Neutral, and Strong) has been added! Riven Disposition is the way in which power level of Mods is attuned to the weapon it is generated for. You can expect to see more powerful Rivens for less used weapons and vice versa.
• Existing Rivens have been automatically rebalanced to fit this Riven Disposition
• When Cycling a Riven with Kuva, you can now choose to "Accept" or "Decline" a Cycle result using the arrow and Confirm button presented.
• You will only have to Unveil a Riven Mod one time: on first discovery. Cycling no longer Veils Riven Mods. *A script has been run tounveil Veiled Riven Mods that have been Cycled. Relog required.
• Adjusted Endo return when dissolving Riven mods:
  • +100 Endo for every Mastery Rank requirement above the minimum of 8
  • +200 Endo for every Cycle performed on the Mod
• Chat Linked Riven Mods now contain correct challenge progress/requirement info, as well as Cycles.
• Kuva Cycling costs have been reduced significantly.

  • Cycle 1: 900
  • Cycle 2: 1000
  • Cycle 3: 1300
  • Cycle 4: 1800
  • Cycle 5: 2500
  • Cycle 6: 3400
  • Cycle 7: 4500
  • Cycle 8: 5800
