Unstable Iso-8 Prismatic


"Special Operations require the resource Unstable ISO-8 to access its mission events, including battles and deploys. You can earn Unstable ISO-8 through battle or deploys, gifts from friends, or buy it from the store to help you complete the challenge. However, once the mission is expired that flavor of Unstable ISO-8 goes away with it, so try to use it all up!"
— Special Operations Briefing

Unstable Isotope-8 (Unstable Iso-8 or  U Iso-8) are used specifically in Special Operations in addition to the normal requirements to initiate each battle or deploy. They are also used for researching various items that are only available from unlocking the Blueprints from completing Spec Op Tasks. Only Special Operations 1 required 5 Unstable Isotope-8 per battle or deploy and had no research. From Special Operations 2 forward, each deploy, incursions and normal battle requires 10 Unstable Iso-8 and each boss battle - Mini, Regular, Epic, and Group Boss - requires 20 U Iso-8 to initiate. Blueprints specific to each Special Operation require 80, 100, or 120 Unstable Iso-8.

Starting with Special Operations 2, with the exception of Special Operations 3, with 550 U Iso-8, each player started with 440 Unstable Isotope-8.

Unstable Isotope-8 that obtained before Special Operations is unlocked may disregard.

  • Previous post Special Operations had Unstable Iso-8 continue to drop in Allies and Combat. They serve no use and does not carry over onto the next Special Operation.
  • There was an Art Bug wherein Special Operations 15 used blue Unstable Iso-8. This was corrected on later updates.
