Jewel of Harmony is created from Gemstone in the Tower of Refine (see above). With the help of Jewel of Harmony, you can add new options to things. The probability of successfully adding an option is 30%.
Harmony options can be added to all weapons, shields, and all parts of sets: regular, Excellent, and Ancient.
Features:
You can add only one option per item.
The higher the level of the item, the higher the chance of getting the best option.
An item with the option cannot be sold (to either players or NPCs), items with the option are automatically assigned to your account. You can always remove the option (in order to sell or transfer the item in the future) from the Jerridon goblin. Of course, you can move things within your account.
Items with Harmony options can be sold in the web store.
To get the option, you need to insert the Jewel of Harmony into the item.
The options are randomly generated.
Luck does not affect the chance of getting an option.
