Disks are special items that heroes can equip and upgrade. Each disk is designed to enhance key traits of the hero who equips it.

Whenever you complete the first episode of a friend campaign, you will unlock a memory disk for the primary hero in the friendship. A memory disk is a permanent memento of the heroes’ friendship!

If a hero has more than one friend, that means that hero can unlock more than one memory disk. But each hero can only equip one memory disk at a time.
