Jewel of Harmony: Complete System of Options and Application in MU Online
Complete guide to the Jewel of Harmony in MU Online S6: how to obtain, apply, remove, and which options each item type can receive.
What is the Jewel of Harmony
The Jewel of Harmony is one of the seven fundamental jewels in MU Online, alongside the Jewel of Bless, Soul, Life, Chaos, Creation, and Guardian. It occupies a unique position in the equipment progression system: while other jewels increase item level, luck, or excellent options, Harmony adds an exclusive bonus called the "Harmony option" directly to the item.
This option functions as an extra layer of attribute — completely separate from the item level (+0 to +15), excellent options, and base attributes — and can transform a mediocre piece of equipment into a high-performance item when the rolled option is favorable for your build.
How to Obtain the Jewel of Harmony
The Jewel of Harmony can be obtained through the following methods in S6:
- Direct drop from monsters in high-level zones (Aida, Karutan, Acheron, and Kalima 6-7 have the best rates)
- Lahap NPC: trade 10 Jewels of Bless or 10 Jewels of Soul for 1 Jewel of Harmony (cost-benefit ratio varies by server economy)
- Box of Kundun (level +4 and +5): chance to contain Jewel of Harmony among possible drops
- Golden Invasions: Golden monsters (Golden Budge Dragon, Golden Titan, etc.) have a chance to drop Harmony
Recommended acquisition flow:
Farm in Aida/Karutan → direct drop of Harmony
↓ (alternative)
Accumulate 10x Jewel of Bless → Lahap → 1x Jewel of Harmony
↓ (boss route)
Participate in Golden Invasion → drop of Harmony + other rare itemsRequirements to Apply Harmony
Before applying the Jewel of Harmony, the item must meet all the criteria below:

| Item state | With or without excellent options (both work) |
| Restriction | Excellent and Ancient items accept Harmony normally |
Harmony Options for Weapons
When the Jewel of Harmony is applied to a weapon (sword, axe, bow, staff, scepter, wand, etc.), the system rolls one of the following options:
| Option | Effect | Notes |

Harmony Options for Armors
When applied to a piece of armor (helm, armor, pants, gloves, boots, or shield), the available options are defensive:
| Option | Effect | Notes |

Application Strategy by Class
Each class in MU Online S6 benefits from specific combinations of Harmony options. The table below summarizes priorities:
| Class | Weapon (priority) | Armor (priority) |
|---|---|---|
| DK → Blade Knight → Blade Master | Max Damage / Critical | Max HP / Defense |
| DW → Soul Master → Grand Master | Spell Damage / Magic Critical | Max Mana / Damage Reduction |
| Elf → Muse Elf → High Elf | Max Damage / Attack Speed | Max HP / Damage Reduction |
| MG → Duel Master | Max Damage / Critical | Max HP / Defense |
| DL → Lord Emperor | Critical / Skill | Max HP / Defense Success Rate |
| Summoner → Bloody Summoner → Dimension Master | Magic Critical / Spell Damage | Max Mana / Mana Recovery |
Removing the Harmony Option
The removal process is simple but costly in terms of jewel consumption:
Item with Harmony (undesired option)
↓
Apply a new Jewel of Harmony over the same item
↓
Previous option is removed → new option is randomly rolled
↓
Jewel is consumed (1 Jewel of Harmony per attempt)
↓
Repeat until the desired option is obtainedThere is no way to remove the Harmony option without applying another jewel. There is also no NPC or Chaos Goblin combination that performs this function separately in S6.
Jewel of Harmony on Ancient Items
The ancient sets in MU Online S6 — such as Hyon (Dragon), Gywen (Bow Elf), Sebone (Bone), Kantata (Scale), Eplate (Energy Plate), Agnis (Legendary), Ceto (Great Dragon), Drake (Dark Steel), Gaia (Dark Soul), Broy (Venom Mist), Sylion (Sunlight), Heras (Ashcrow), Chrono (Divine), Anubis (Anubis), Enis (Red Spirit), and Aruan (Thunder Hawk) — all accept Harmony normally.
Interaction with Other Enhancement Systems
The Jewel of Harmony works completely independently from other item improvement systems:
| System | Interacts with Harmony? |
|---|---|
| Jewel of Bless / Soul (item level) | Does not affect the Harmony option |
| Jewel of Life (excellent options) | Independent, separate slots |
| Jewel of Chaos (Goblin mix) | Resulting item can receive Harmony |
| Jewel of Guardian (socket) | Not applicable in S6 for Harmony |
| Excellent Options (up to 6 options) | Cumulative with Harmony |
| Ancient Set Bonus (2/3/4 pieces) | Cumulative with Harmony |
The final result of an optimized item in S6 can combine: level +15 + excellent options + ancient bonus + Harmony option, forming four independent layers of attribute on a single piece of equipment.
Conclusion
The Jewel of Harmony is one of the most important customization tools in MU Online Season 6. Unlike systems from later versions, in S6 it represents the top of the individual item enhancement hierarchy — there is no Flame of Condor in this version. Understanding which options to prioritize for your class, how to plan application on ancient sets, and when it is worth rolling again are skills that separate casual players from those who extract the maximum potential from their character.
Perguntas frequentes
What is the Jewel of Harmony?
It is a special jewel in MU Online that adds an extra option to an already enhanced item, separate from excellent options and sockets. Each application randomly defines one option from the group corresponding to the item type (weapon or armor).
Can I choose which option the Jewel of Harmony gives?
No. The option is determined randomly from the pool of options for that item group. Weapons receive damage/speed options, armors receive defensive options. There is no way to force a specific option without removing and reapplying.
How do I remove the Harmony option without destroying the item?
Apply a Jewel of Harmony again over the same item that already has a Harmony option. This removes the existing option (the item reverts to its previous state) but consumes the jewel. The item is not destroyed in this process.
Does the Jewel of Harmony work on any item?
No. Only items at level +4 or higher accept the Jewel of Harmony. Jewels, pets, rings, and pendants cannot receive Harmony. Excellent, ancient, and normal items of adequate level are all compatible.
What is the difference between Harmony and an excellent option?
Excellent options are fixed on the item since it dropped and depend on their own roll. The Harmony option is added manually by the player using the jewel and can be removed and reapplied. They are independent and cumulative bonus slots.
