Dungeon Defenders

You will need a piece of equipment (weapon or armor) that has at least 2 upgrade levels. When you’re in the Tavern, during the Build Phase in between waves of enemies, you can upgrade your equipment by accessing the Lockbox and locating the piece of equipment you wish to upgrade in either Hero Info (if equipped) or Item Box (if stored). Press to access the Item Info screen, and press to invest mana to upgrade the equipment. You can also do this at the Barkeep in the Tavern.
