In the world of MU Online, there is an opportunity to add additional options to regular and Excellent items, which will help the player in the difficult development of our game world. Such options are called Harmony options and can be added using special stones - Jewel of Harmony, which, in turn, are obtained from Gemstones.

Obtaining Jewel of Harmony stone

The Jewel of Harmony stone can be obtained by refining stones called Gemstone, which can be knocked out of all monsters in the KanturuRelics location and from the Red Dragon in the Lorencia location (185x120) during the Red Dragon Invasion. To do this, you need to go to the Gateway Machine, which is located in KantruRelics (141x186) during the Kanturu event (you must put on the Moonstone Pendant, without it you will be thrown out of the event), after a successful victory, you will be able to use the functions of NPC Elpis within 10 hours. You need to click on the Refine Gemstone button. In the 4x8 window that opens, put one Gemstone and click on the Refine button. As a result, we get a purified Jewel of Harmony stone.
Attention! The chance of purification is 80%, in case of failure the Gemstone will burn.

To add an additional Harmony option to an item, drag the Jewel of Harmony stone onto the item. The chance of getting the option is 75%, "Luck" does not affect the success of adding. If the enchantment is successful, the item will have an additional option highlighted in yellow. Options are added randomly and depend on the enchantment level of the item: the higher the enchantment level, the more powerful the options will be when enchanted with the Jewel of Harmony stone, below is a graph with options and the minimum item level to get the option.
Please note: You can only add one option.

In the Aida location, it is possible to remove unnecessary options from things with the help of NPC Jerridon (86x13) or get Higher Refining Stone and Lower Refining Stone from NPC Osbourne (78x13), with which you can improve existing options.
