Chaos Machine Success Rates (+10 to +15) and TCA Protection
Exact success formulas, jewels required per level, consequences of failure, and why the Talisman of Chaos Assembly (TCA) is essential.
⚙️ Chaos Machine: Upgrading Items from +10 to +15
The Chaos Machine (Chaos Goblin in Noria: 180, 103) allows you to forge items from +10 up to +15.
📊 Real Requirements and Probabilities (Rex Mu):
Rates in effect at the time of writing this guide (the server's live API may adjust them):
| Target Level | Jewels Required | Base Success | Consequence on Failure |
|---|---|---|---|
| +10 | 1x Bless, 1x Soul, 1x Chaos | 40% | The item may be destroyed |
| +11 | 2x Bless, 2x Soul, 1x Chaos | 40% | The item may be destroyed |
| +12 | 3x Bless, 3x Soul, 1x Chaos | 35% | The item may be destroyed |
| +13 | 4x Bless, 4x Soul, 1x Chaos | 30% | The item may be destroyed |
| +14 | 5x Bless, 5x Soul, 1x Chaos | 30% | The item may be destroyed |
| +15 | 6x Bless, 6x Soul, 1x Chaos | 25% | The item may be destroyed |
No level requires Jewel of Creation.
We don't have a confirmed fixed Luck bonus for this specific table: the +25% that appears in other Rex Mu contexts corresponds to the creation of Jewel of Soul, not to upgrading items from +10 to +15. Don't apply it here without confirming it.
🛡️ What is the TCA (Talisman of Chaos Assembly) and why is it VITAL?
- The TCA (Talisman of Chaos Assembly) is a talisman placed in the Chaos Machine alongside your items.
- Function: If the combination FAILS, the TCA prevents losing the item, according to its official description. The exact behavior after a failure (whether the level drops or stays the same) is not confirmed with the available data.
- ⚠️ NEVER attempt to upgrade a valuable item to +10, +11, +12, +13, +14 or +15 without a TCA, unless you're willing to risk losing the item.
