ISO-8 is an upgrade item used to level up champions. There are two types of ISO-8: basic ISO-8 and class ISO-8. Using class ISO-8 on the same class of champion provides a 50% bonus, thus indirectly reducing the amount of gold used to level up a champion. Currently, there are five tiers of ISO-8. Each tier determines the amount it contributes to the levelling of the champion.

ISO-8 gained through gameplay can expire after a certain amount of time, and is permanently lost. ISO-8 is also lost if the amount used is more than the amount required by the champion upon reaching maximum level (for that rank).
