Armor

To enhance your armor, go to the General menu and select Enhance Item, or simply double-click on an Armor Enhancement Card to open the Enhancement window.

Drag your Armor Enhancement Card into the Card slot and your armor piece into the Item slot and click the Enhance button to start.

Armor can be enhanced upto 10 times and each successful enhancement gives your piece of armor extra Physical and Magical Defense.

Armor Enhancement Cards can be purchased from Nojacque in Terminus.

Weapon

Weapon enhancement works exactly the same as armor but you need to use Weapon Enhancement Cards.

Weapons can also be enhanced upto 10 times and each successful enhancement gives your weapon extra Physical Attack or Magical Attack & Healing depending on the weapon type, and a glow effect that gets stronger the higher the enhance level.

Generally, Swords, Daggers and Guns gain Physical Attack, Staves and Rods gain Magic Attack & Healing and Shields gain Physical and Magic Defense.

Weapon Enhancement Cards can be purchased from Nojacque in Terminus.
