Gathering Tips

  • Kuva Lich and Arbitrations missions can spawn Eximus units more often as a result of their higher level, allowing for easier farming.
  • Any Endless mission types on Europa is a great source for Eximus units, the longer you stay the more Eximus units will spawn.
    • Ose, Europa is an Interception mission that can yield a moderate amount of Cubic Diodes.
    • Larzac, Europa is a Dark Sectors defense mission with high eximus spawn rate and is increasingly helpful as Infested Electric Crawlers count as Eximus
  • Nereid, Neptune is a Spy mission with the Corpus Ice Planet tileset. Eximus units are guaranteed to spawn if a player triggers the alarms in a vault.
  • Syndicate Death squads will also drop these if they spawn on the Corpus Ice Planet tileset as they all spawn as Eximus units.

Notes

  • Cubic Diodes can be found on Neptune too on Nereid and Neso nodes which have the Corpus Ice Planet tileset.
  • Marduk is a Sabotage mission in the Void has a Corpus Ice Planet tileset when fighting the Lynx. Players may also get Cubic Diodes if Eximus units spawn in this tileset or in the Orokin Tower tileset during that mission.

Patch History

Hotfix 26.1.2 (2019-11-25)

  • Swapped the planet locations of Cubic Diodes and Carbide to match their Resource type:
    • Cubic Diodes = Eximus units on Europa Ice Planet tileset
    • Carbides = Eximus units on Ceres Shipyard tileset
  • Fixed Cubic Diodes and Carbide Resources not dropping 50% of the time. For further clarification, on-kill extra drops (like Khora and Hydroid) do not apply to these Resource drop type: Cubic Diodes and Carbides have a 100% chance to roll the table for a 50% chance, can't boost that 100% any further!
  • Fixed various issues with ground-mission Cubic Diodes and Carbide pickups, such as: Waypointing them resulted in a generic waypoint and not an item specific tag, and pickup FX being removed as soon as someone picked them up resulting in confusion as to where the Resource actually is on the ground.

Update 26.1 (2019-11-22)

  • Introduced.
