There are several different types of items in the game, and you might lose track of them from time to time. Here’s the breakdown of each type just in case you needed a reminder:
Equipped to your characters while you assemble your team. Weapons improve the combat potential of the character equipping them. The rarity of a weapon will help determine it’s value and potency, so keep an eye out for the rarest items in your arsenal.
Received only from battles, used to upgrade characters.
Special items that are crafted in the workshop, used only during mission battles when loaded into your team setup.
Received only from battles, and used to research and Craft various Battle Items.
These items may be found during battle or purchased from the shop. At this point, the only items in this category are World energy refill, raid energy refill, and radios (bronze, silver, gold).
