Chaos Goblin Guide: All Combinations and Rates in MU Online
Complete Chaos Goblin guide for MU Online S6: all combinations, success rates, required ingredients and tips to avoid wasting your Jewels.
The Chaos Goblin is the most important crafting NPC in MU Online. Located in Noria at coordinates 170, 102, he is responsible for transforming ordinary materials into powerful equipment — and for destroying everything if you do not know what you are doing.
This guide covers every combination available in Season 6, with exact success rates, required ingredients, and practical tips to maximize your results.
What Is the Chaos Goblin
The Chaos Goblin accepts crafting recipes in exchange for Zen. Each recipe requires specific ingredients, and the outcome — success or failure — is determined by a probability rate set on the server. On failure, all ingredients are destroyed without exception.
There are two main categories of combinations:
- Regular: item level upgrades, pet creation, and special weapon crafting
- Advanced: Fenrir creation, level 380 item combinations, and accessory crafting
Level Upgrade Combinations
The Chaos Goblin upgrade system differs from regular upgrading with Jewel of Bless and Soul. Here, you skip level brackets in a single attempt, but the risk is significantly higher.
Upgrade +10 to +12
To raise an item from +9 to +10, then from +10 to +11 or +12:
Item at +9 or higher
→ + Jewel of Chaos x1
→ + Zen (variable by item type)
→ Success rate: 60% (+10), 55% (+11), 50% (+12)Upgrade +13, +14, and +15
The riskiest upgrades in the game. From +13 onward, the success rate drops sharply:
| Target Level | Success Rate | Zen Required (approx.) |
|---|---|---|
| +13 | 45% | 7,000,000 |
| +14 | 40% | 9,000,000 |
| +15 | 35% | 11,000,000 |

Advanced Tips for the Chaos Goblin
Risk management: Never attempt a high-level upgrade without enough Zen for multiple tries. If you only have one copy of a rare item, consider farming or trading for two or three copies before attempting +13 or above.
Crafting order: Always complete your level upgrades before applying Jewels of Harmony or high-value Excellent options. This way, if the craft fails, you lose less total value.
Ingredient farming: Fenrir Fragments drop from monsters in Tarkan and from certain in-game events. Loch's Feather is a drop from the Horn of Fenrir monster. Plan your farming session before you start crafting.
Combining with events: Some server events temporarily increase the Chaos Goblin's success rates. Pay attention to server announcements to take advantage of these bonuses.
Perguntas frequentes
What happens if a combination fails?
On failure, every single ingredient is destroyed and the Zen spent is not refunded. High-level combinations like +15 have success rates below 50%, so always assess whether you can afford to lose everything before attempting the craft.
Can I combine Excellent items in the Chaos Goblin?
Yes. In most level upgrade combinations (+10 through +15), the Excellent options on the base item are preserved if the craft succeeds. They are only lost on failure, along with the item itself.
What is the difference between Chaos and Creation in the Chaos Goblin?
The Jewel of Chaos is the mandatory core ingredient in almost every combination and is consumed whether the craft succeeds or fails. The Jewel of Creation is required for more advanced recipes such as Fenrir creation and high-tier item crafting, and is also consumed regardless of outcome.
How does Tier 7 (level 380) weapon crafting work?
Level 380 items require a base item at +9 or higher with an Excellent option, Jewel of Harmony, Jewel of Chaos, and Jewel of Creation. The success rate is approximately 50%, and the resulting item will have a random Harmony option applied to it.
