Equipment extractions are one of the more routine methods of obtaining gold leaves in Maplestory M. You sacrifice an equipment, pay a meso cost, and the game rewards you with some amount of gold leaves (and occult cubes) as a result:
| Equipment Rank | Gold Leaves | Occult Cubes |
| Normal | 0-7 | 0-1 |
| Rare | 0-29 | 0-2 |
| Epic | 0-73 | 0-3 |
| Legendary | 0-293 | 0-6 |
So, normal ranked equipment gives you from 0 to 7 gold leaves. But, have you noticed that you seem to get 0 gold leaves more frequently than you should?—assuming that you are equally likely to get 0, 1, 2, …, 7 gold leaves for each extraction.
It turns out that the probability of getting 0 gold leaves is much higher than the probability of getting 1 gold leaf, or 2, or 3… all the way up to 7! In fact, based on 242 individual extractions, it looks like the odds of getting 0 gold leaves is roughly 50%, while the odds of getting 1 or 2 gold leaves is 0%!
The estimated probabilities from this data are shown in the table below. It’s probably safe to say that the odds of getting 3 to 7 gold leaves are roughly equal.
| Gold Leaf Yield per Normal Extraction | Estimated Probability |
| 0 | 47% |
| 1 | 0% |
| 2 | 0% |
| 3 | 8% |
| 4 | 12% |
| 5 | 11% |
| 6 | 10% |
| 7 | 12% |
What can we conclude from this table? Well, if we round up each probability to the nearest 10%, we find that the average extraction of a normal equipment will give you 2.5 gold leaves.
(50% × 0) + (10% × 3) + (10% × 4) + (10% × 5) + (10% × 6) + (10% × 7) = 2.5
(If each probability were the same, you would expect an average of 3.5 per extraction!)
Obviously, this is not a very efficient way of obtaining gold leaves. Fortunately, there are many other legitimate ways to obtain gold leaves in Maplestory M: read more about them in my previous post.
