Stable and Unstable Upgrader Combination Success Rate
The good news is RFDB (the writer) already spoil about Stable and Unstable Upgrader Combination Success Rate. Kindly take a look on this page:
>> Stable and Unstable Upgrader Combination Chance Success Rate <<
- In RF Online, 0.1% chance rate in combination mean that it’s still possible (with very small percentage rate). If you ever found an 5-6D upgrader in celeb medium box, or rare d weapons dropped from Pitbosses. It is same 0.1% rate too, so don’t lose hope 😀

Pro Tips
When opening Ignorant Box or Favor Box, you will get random upgraders. Make sure to keep the good upgraders like:
| 4~6 Ignorance Upgrader [B-Class] |  Unstable4~6 Ignorance Upgrader [B] |
| 4-6 Ignorance Upgrader [Rare D] |  Stable 4-6 Favor Upgrader [Rare D] |
 5~6 Ignorance Upgrader [B-Class] | Unstable 5~6Favor Upgrader [B-Class] |
| 4-6 Ignorance Upgrader [Rare D] |  Unstable 4-6 Ignorance Upgrader [Rare D] |
Always recycle below 3~5 upgraders like 1~2, 1~3 1~4 2~4 just recycle it, to get a Celebration Box<Large> or Favor Lucky Box<Large>.
If you have same type of weapons or armors in many quantities, you may try to combine it with unstable upgraders. Because it will produce higher talics result rather than stable one (take a look: upgrader success rate).
Thanks for reading, good luck ~
