Characters can equip up to 4 pieces of equipment items.
Each item has a rarity, stat boost and set symbol.
Equipping 4 items with identical set symbols will give you a Set Bonus, which will further increase your character’s stats. The type of Set Bonus you receive depends on the set symbol attached to the equipped items.
The rarity of an item will decide the magnitude of the item’s stat boost and the amount of Set Bonus you can receive (the amount of the Set Bonus will depend on the lowest rarity item out of the 4).
You can increase the rarity of an item by upgrading them. Upgrading an item will require you to consume other items as ingredients.
