Jewel of Chaos and Jewel of Creation: complete crafting guide

Jewel of Chaos and Jewel of Creation are the combination jewels of MU Online — while JoB and JoS handle upgrading items level by level, Chaos and Creation are what you feed into the Chaos Goblin Machine to CREATE entirely new items. Every Wing, every Fenrir, every Dinorant begins with these two jewels.

Jewel of Chaos — the universal catalyst

What it does:

Jewel of Chaos is required in the recipe for EVERY Chaos Goblin combination:

Always required:
→ Wing L1 (any class): 1x JoChaos in recipe
→ Wing L2: 1x JoChaos in recipe
→ Wing L3: 1x JoChaos in recipe (plus other materials)
→ Fenrir Stage 1 (Broken Horn): 1x JoChaos
→ Fenrir Stage 2 (Fenrir Blue): 1x JoChaos
→ Dinorant (Stage 1 and 2): 1x JoChaos per stage
→ Sealed Kalima Gate: 1x JoChaos
→ Ancient item combinations: 1x JoChaos
→ Essentially every other combination: 1x JoChaos minimum

Without JoChaos: you cannot do any combination at Chaos Goblin

Where JoChaos drops:

From monsters throughout the game:
→ Starts dropping in Dungeon / Lost Tower areas
→ Better rate in: Tarkan, Aida, Kanturu
→ Drops from essentially any monster at mid-level+ maps
→ Common enough that accumulation is straightforward

Event rewards:
→ Blood Castle: JoChaos occasionally in completion rewards
→ Devil Square: JoChaos in rewards
→ Monster invasions: sometimes drop

Market price:
→ JoChaos is NOT as valuable as JoB
→ Typical price: 0.5-2 JoB per JoChaos (server-dependent)
→ Not the limiting factor in any combination — JoCreation or Loch's Feather is

---

The "Blessed Chaos" technique:

How it works:
→ Add MORE JoChaos than the minimum required in a combination
→ Some combinations allow 2, 3, 5, or more JoChaos slots
→ Each extra JoChaos: +X% to success rate (varies by server/combination)

Example (Wing L1 with extra JoChaos):
→ Minimum: 1x JoChaos (base rate: ~70%)
→ With 2x JoChaos: ~75%
→ With 5x JoChaos: ~85% (maximum boost, server-dependent)

When to use blessed chaos:
→ High-value combinations where failure is painful
→ Wing L2 and L3 especially
→ Fenrir Stage 2 (Claw of Beast is expensive to lose)

Cost-benefit:
→ JoChaos is cheap (~1-2 JoB each)
→ Adding 4 extra JoChaos costs ~4-8 JoB
→ If it prevents one Wing L2 failure (saves 60-200 JoB): absolutely worth it

Jewel of Creation — the rare essential

What it does:

Jewel of Creation is used in:
→ Wing L3 crafting (primary use — requires 1x JoCreation per attempt)
→ Some other advanced combinations (varies by server)
→ NOT needed for Wing L1, Wing L2, Fenrir, Dinorant

Without JoCreation: you CANNOT craft Wing L3

WHERE JEWEL OF CREATION DROPS IN SEASON 6:

ONLY THREE SOURCES:

1. Kundun (in Kalima 7):
→ Entrance: Sealed Kalima Gate of the highest level
→ Kundun is the final boss of the Kalima dungeon
→ JoCreation drops on boss kill
→ Requires group (Kundun is very powerful)
→ Drop rate: low (not guaranteed per kill)

2. Nightmare (in Kanturu 3 — Kanturu Relics):
→ Most commonly farmed JoCreation source in S6
→ Nightmare is the boss of Kanturu 3 (deepest floor)
→ Drops JoCreation on kill
→ Requires group — Nightmare is a difficult boss
→ Drop rate: moderate (better chance than Kundun, more accessible than Selupan)

3. Selupan (in Raklion):
→ Hardest boss in Season 6
→ Requires 8-15 organized players minimum
→ Drops JoCreation (and best items in S6)
→ Drop rate: can be moderate to good (Selupan's loot table is the best in S6)

IMPORTANT: JoCreation does NOT drop from regular field monsters.
NOT from Blood Castle rewards, NOT from Devil Square completion.
ONLY from these 3 bosses.

---

Economic implications of this scarcity:

Why Wing L3 is so expensive:
→ Wing L3 requires 1x JoCreation per attempt
→ JoCreation only comes from 3 boss sources
→ If Wing L3 attempt fails: that JoCreation is gone
→ A server with 50 players farming Nightmare 3x per day = maybe 15-30 JoCreation per day
→ Every Wing L3 attempt = 1 JoCreation less available

Price of JoCreation:
→ Typical S6 mid-rate: 30-100 JoB per JoCreation
→ High-rate or large server: 30-50 JoB
→ Low-rate or new server: 80-150 JoB
→ The price directly reflects how often players kill Nightmare/Kundun/Selupan

---

Farming JoCreation efficiently:

Best strategy per boss:

Nightmare (recommended for most groups):
→ Requires: level 360+, decent gear, 5-8 players
→ Located in Kanturu 3
→ Entry requirement: Lochfeather's Soul or specific access quest (server-dependent)
→ Spawns regularly (check server schedule)
→ Drops: JoCreation + excellent items + rare drops

Selupan (best loot but hardest):
→ Requires: level 380+, excellent gear, 8-15 organized players
→ Located in Raklion
→ Selupan's Arm mechanic: must be positioned correctly
→ Drops: JoCreation + best items in S6 overall

Kundun (least recommended):
→ Requires Kalima 7 access (expensive tickets)
→ Ticket cost: Lost Maps + JoChaos combination
→ Kundun is strong but drops are less reliable per run cost
→ Better to farm Nightmare instead

---

Group composition for JoCreation farming:

Recommended group:
→ 2-3 DK tanks (absorb boss damage)
→ 2-3 DW DPS (primary damage dealers)
→ 1 Elf REQUIRED (heals DK tanks — without Elf the DKs die too fast)
→ Optional: DL for group command utility

Without Elf:
→ DK tanks die during extended boss fight
→ Entire run fails
→ Elf presence is not optional for consistent JoCreation farming

JoChaos vs JoCreation — direct comparison

Comparison table:

Feature          | Jewel of Chaos          | Jewel of Creation
-----------------|-------------------------|-------------------
Use              | All combinations        | Advanced (Wing L3)
Frequency needed | Multiple per session    | 1 per Wing L3 attempt
Drop source      | All mid-level monsters  | ONLY Kundun/Nightmare/Selupan
Rarity           | Common                  | Rare to very rare
Price (JoB)      | 0.5-2 JoB each          | 30-100 JoB each
Failure impact   | Low (cheap to replace)  | High (expensive to replace)
S6 primary use   | Wing L1, L2, Fenrir     | Wing L3 only

---

Economic role:

JoChaos:
→ The "oil" that keeps the combination machine running
→ Low individual value, high cumulative use
→ Stocking up: have 50+ JoChaos before any major combination session

JoCreation:
→ The "scarcity valve" of S6's economy
→ Because it's rare: Wing L3 remains expensive regardless of other factors
→ Even on x1000 rate servers: if Nightmare/Selupan drop rates are default = JoCreation is rare
→ Server admins who increase JoCreation drop rates: Wing L3 prices collapse

---

Inventory management:

JoChaos: stack as many as you can accumulate (stacks in inventory)
JoCreation: keep in vault when not using (safer than inventory in PvP servers)
