World of Warcraft - Item Upgrading Players can upgrade their weapons, armor and trinkets. Certain upgrades can have special effects while others boost numeric stats. The upgrades to items are an essential part of the Path of Exile progression. They can increase damage to ships and gear and overall effectiveness in combat. Typically items that don't vary in terms of requirements following upgrading (like Eth Titans) will see a slightly less trade value than the unupgraded versions. Recycled
