Fuse giving out clean equips...

Didn't one of the KMSers mass combine like a hundred jean shorts or something? I know i saw it but i can't find it. It'd be nice to compare the numbers.

Here are GMST numbers:

In the name of SCIENCE I shall forge together some shoes and log the results.
Level 20 Pirate Shoes, to be precise (10 def, no other stats).
Clean + Clean With lv.1 Alchemist
Average no-pot: IIIII II
3L Rare: I
2L Rare: I
Final: 9 shoes made, all average stats, 22% hidden pot. "premium percent 0%"

Clean + Clean With lv.2 Alchemist
Average no-pot: IIIII IIIII IIIII
Below average no-pot: I
2L Rare: III
Above average 2L Rare: I
2L Epic: I
Final: 21 shoes made, 19/21 average stats, 24% hidden pot. premium 4.7%, crappy 4.7%

Clean + Clean With lv.3 Alchemist
Average no-pot: IIIII IIIII IIIII I
Below average no-pot: IIIII
Above average no-pot: II
Below average 2L Rare: I
3L Rare: IIIII
(note: I was reforging below/above average stat items separately but they all came out average)
Final: 29 shoes made, 21/29 average stats, 21% hidden pot. premium 6.9%, crappy 20.7%

I had a lot of 2L/3L so I decided to try recombining at this point.
Clean + 3L With lv.3 Alchemist
Average no-pot: IIII
Below Average no-pot: I
Conclusion: Clean + Potted items is a bad idea.
2L Rare + 2L Rare With lv.3 Alchemist
Below Average 2L Rare: III
2L Rare: I
3L Rare: I
3L Rare + 3L Rare With lv.3 Alchemist
2L Rare: I
Tentative conclusion: As good as super miracle cubes, on rare items anyway. Bad to use on 3L items though.

Clean + Clean With lv.4 Alchemist
Average no-pot: IIIII IIIII IIIII IIIII IIIII IIIII IIIII II
Below Average no-pot: IIIII II
Above Average no-pot: I
2L Rare: IIIII
3L Rare: II
2L Epic: I

Clean + Clean lv.10 Pirate Shoes, to see if level greatly affects things. Evidently it doesn't.
Average no-pot: IIIII
2L Rare: I
Final: 59 shoes made, 51/59 average, 15% hidden pot. premium 1.7%, crappy 11.9%

2L Rare + 2L Rare with Lv. 4 Alchemist
Above average clean: I
Below average 2L Rare: I
3L Rare: I
3L Rare + 3L Rare
2L Rare: I

Clean + Clean Level 5 Alchemy
Average clean: IIIII IIIII IIIII IIIII IIIII IIIII IIIII IIIII IIIII IIII
Below average clean: IIIII IIIII IIII
Above average clean: IIIII I
Below average 2L Rare: II
2L Rare: IIIII I
Above average 2L Rare: II
Below average 3L Rare: II
3L Rare: I
Above average 3L Rare: I
(note: more below average here 'cause I switched to using the level 40 gear, which has more stats. However, "premium equip" above average seems to mean all stats average or higher. )
Final: 83 equips made, 56/83 average, 17% hidden pot, premium 10.8%, crappy 21.6%

2L Rare + 2L Rare
2L Rare: III
Above average 2L Rare: I
3L Rare: II
Above average 3L Rare: II
3L Rare + 3L Rare
2L Rare: II


Cumulative results, level 1 ~ 5:
201 equips made.
36 with hidden potential = 18%
2 epic on reveal = 5.5% of those with hidden potential
12 with 3 lines = 33% of those with hidden potential

20 equips made from 2 with hidden potential
16 with 2 lines, 4 with 3 lines started - all 4 with 3L became 2L.
6/20 with 3 lines = 30% of those with hidden potential


Clean + Clean level 6 Alchemy
average: IIIII IIIII IIIII IIIII IIIII IIIII IIIII IIIII
below average: IIIII IIIII IIII
above average: IIIII IIIII IIIII IIIII
below average 2L rare: IIII
2L rare: IIIII IIIII I
above average 2L rare: I
below average 3L rare: I
3L rare: IIIII I
above average 3L rare: II
below average 3L epic: I
Final: 100 equips made, 57/100 average, 26% with hidden pot, premium 23%, crappy 20%.

2L Rare + 2L Rare
below average 2L rare: II
2L rare: IIIII I
above average 2L rare: I
below average 3L rare: I
3L rare: II
3L Rare + 3L Rare
no potential: I
below average 2L rare: I
2L rare: I
above average 2L rare: II
2L epic: I
2L epic + 2L epic
3L rare: I

Totals:
301 fusions of clean no-potential equips
62 with hidden potential = 20.6%
3 with epic potential = 4.8% (of those with potential) / 1% (of all equips)
22 with 3 lines = 35.5% (of those with potential) / 7.3% (of all equips)

39 fusions of potential equips
37 with hidden potential = 94.9%
1 with epic potential = 2.7% (of those with potential)
10 with 3 lines = 27% (of those with potential)

99 hidden potential items produced
4 with epic potential = 4%
32 with 3 lines = 32%

So, the level of your alchemy increases the chance of better potential on fused equips?

When reading the description, it says that fusing two POTENTIAL items (no matter if hidden or revealed) you will ALWAYS get a hidden potential item back. The current stats on the item do NOT matter. This means that if you're fusing two unique items, you will ALWAYS get a hidden potential item back, but it's not guaranteed to be unique again.

When fusing a hidden potential item with a clean item (non-potential), you'll have the same chance of getting a hidden potential item back as well as fusing two clean items together.

The description is wrong. I have got a non potential item when fusing two potentialed ones. Other have confirmed this as well.
