Mu Online Chaos Machine — Combinations & Rates

Every recipe with its default success rate

The Chaos Goblin in Noria is where +10 to +15 items, every wing tier, Fenrir and event tickets are made — and where most of the game's jewels disappear. This guide lists what goes into each combination and the maximum success rate the server actually uses, read from the default Season 21 server files rather than guessed.

Item +10 to +15

Up to +9 you drag jewels onto the item: Jewel of Bless for +1 to +6 and Jewel of Soul for +7 to +9. From +10 upward the only way is the Chaos Machine. Each step needs one more Bless and Soul than the last, plus one Jewel of Chaos and a Zen fee that the machine window shows before you press Combine.

The rates below are the maximum success rates in the default server files — the machine window starts lower and climbs to this cap as you add value. They are set separately for four kinds of item:

TargetWhat goes inNormal itemsExcellent / setSocket itemsPentagrams
+10+9 item + 1 Bless + 1 Soul + 1 Chaos60%50%50%60%
+11+10 item + 2 Bless + 2 Soul + 1 Chaos60%50%50%55%

+15+14 item + 6 Bless + 6 Soul + 1 Chaos50%40%40%30%

An item with Luck adds +25% on top, and a Talisman of Luck adds up to +10% more. On failure the jewels are always lost; what happens to the item depends on the server version, which is why many players protect expensive items with a Talisman of Chaos Assembly.

Private servers change these numbers often — “high rate” servers commonly run +10 to +15 at 70–100%. The table is the untouched default.

Wing combinations

Every wing tier is made here. Wing class is random in the default files — a Dark Knight can combine a Summoner's wing — unless the server turns on class-locked wing creation. Full stats and pictures of every wing are in the wings list.

3rd and 4th wings can be made either through the classic feather route or the newer wing-relic route, which is why the file carries two rates.

Other combinations

Fenrir, event tickets, SD potions and the newer systems. Rates are the default maximums.

What is the success rate for +15 in Mu Online?

In the default Season 21 server files the maximum is 50% for normal items and 40% for excellent and set items, plus 25% if the item has Luck. Private servers often raise these.

A +12 item, 4 Jewels of Bless, 4 Jewels of Soul and 1 Jewel of Chaos, plus the Zen fee.

Not on default settings - the class is random. Servers can switch on class-locked wing creation, and some sell a Talisman of Wings that fixes the result.
