What it is
The Jewel of Harmony puts a harmony option (shown in yellow) on certain equipment. It is made by refining a Gemstone: put Gemstones in the Gemstone Refining window, pay 50,000 Zen each, and each one may turn into a Jewel of Harmony depending on the success rate. Gemstones come from the Kanturu Maya zone, and since Season 16 Jewels of Harmony also drop in the Elite Zone, with a weekly drop limit.

The Season 16 renewal
Since Season 16| Topic | Before | After |
|---|---|---|
| Items | +0 normal and Excellent weapons and armor | +0 Excellent, socket and set weapons and armor |
| Trading | Items with a harmony option could not be traded | They can be traded |
| Options | 1 option; how many depended on the item's level | 1 to 3 random options, same for any item level |
| Refining stones | Raised the option value (Lower 20%, Higher 80%) | Grant a bonus option; Higher stones also pay for removing options |
Items that had the old harmony option keep it, but refining stones no longer work on them. Granting a new option replaces the old one.
Granting and removing options
Everything is done through Jerridon and Osbourne in Aida. Register the item in the grant window (the jewel is added by itself), pay 100,000 Zen and press Grant. The new options, their values and the maximum they could reach appear under New Options, but nothing is applied until you press Confirm Option.
| Grade | Color | Example |
|---|---|---|
| Lower | White | Strength +10 |
| Middle | White | Strength +15 |
| Greater | Blue | Strength +20 |
| Ultimate | Pink | Strength +30 |
To remove all harmony options (and any bonus option), use the removal window with Higher Refining Stones and Zen: 200,000, 400,000 or 800,000 depending on how many options the item has.
Option types
| Item | Options after Season 16 |
|---|---|
| Sword | Strength, Agility or Energy up, attack success rate, attack, critical and Excellent damage, Skillpower, durability, SD reduction rate, convert 5% of MP to attack |
| Staff / Scroll | Same idea, with Wizardry (staff) or Curse (scroll) instead of attack, and 5% of MP converted to Wizardry or Curse |
| Armor | Vitality, defense, max AG, HP and MP, HP and MP auto recovery, damage reduction, durability, SD ratio, convert 10% of MP to HP |
Refining stones and bonus option
- Craft a Lower Refining Stone from a normal weapon or armor at +4 or higher, and a Higher Refining Stone from an Excellent one at +4 or higher. The fee is 150,000 Zen, success is not guaranteed, and items that already have a harmony option cannot be used.
- Drag a refining stone onto an item whose 3 harmony options are all Greater grade or better. On success it gains or raises a bonus option (Lower stone 10%, Higher stone 50%); on failure the bonus option disappears.
- The bonus option lowers the Strength/Agility requirement in 5 stages, from +10 to +50.
