Functional Isotope-8

Functional Isotope-8 (or Functional Iso-8, F-Iso, F-Iso-8) is used to grant new actions to a hero's move set. Unlike the original Isotope-8, Functional Iso-8 is similar to Augmented Isotope-8 and extends move actions to gain Multi-Function options. These actions are accessed as a normal Multi-Function would be, and increase the variety and potential of heroes, while also allowing users to customize their strategies.

Functional Iso-8 can be placed in any Augmented Isotope-8 Slot, granting that move one or more Multi-Function actions. This means that an A-ISO and F-ISO cannot be slotted on the same move simultaneously.

Much like the Empowered Iso-8 and Augmented Iso-8, inserting an Functional Iso-8 is reversible. When removed, the Iso-8 simply returns to your inventory to be used by later. This would then allow you to once again socket an Augmented Iso-8 on the move. Hint: You can move F-Iso from one hero to another when you click on equip and on the F-Iso screen click on the equipped tab, you can drag the one you want onto the current hero. Like E-Iso and A-Iso, F-Iso cannot be socketed into the Armory as they don't have PVP Bonus.

As of yet, Functional Iso-8 cannot be acquired by any means.

Each Functional Iso-8 can be sold for.
