Many people talking about enchanting. I fact they just like to gamble...(and lost money). But - exist some things which need to know.
So... we have:
1. Enchanting rates can find for most items in l2wiki, some eu/ru forums (admins test) and etc. This is stable - no one official server not changing that rates.
2. Luc stat - which can spam some 'luc lady". Its triger - if get luc lady" - enchant chance 100%. This stat NCSoft sometimes changing - in bad side. We dont know that stats chances - but we can test.
3. Enchanting "spikes" or "windows" - i cant prove, but its only 1 way to explain why sometimes we can enchant item just with 10 scrolls to +10. This "windows' its random - like .. dmg differential 20% -20% or +20.

Allso we have oficial chances:
Enchanting level
Chance
0 → +1
50%
+1 → +2
45%
+2 → +3
40%
+3 → +4
30%
+4 → +5
15%
+5 → +6
10%
+6 → +7
10%
+7 → +8
10%
+8 → +9
10%
+9 → +10
10%
And count how much enchants will need for +5
0.5*0.45*0.4*0.3*0.15=0.00405 chance to get +5 if luc stat +0
Recount to scrolls = 1/0.00405=246.91 scrolls
My test result was 233.70 scrolls
So we see that also working LUC stat. I make some calculation how much was efected wit luc bonus:

Sad. But after last update my 93luc - give for me just 0.47% luc lady shance.
Its not all table - im was lazy to write all. Im use 18.000 scrolls and get +7 bracelet. I was calculated oficial rates and see that will need 24.661 scroll - and I use "just" 18.000 - so i get "personal luc'
PS.: not need talk about mistic GOD and write cirkus how triger working. Its simple "oficial chance + (1-oficial chance) * luc chanse". For example shance 10% an luc shace 9% = 0.1+(1-0.1)*0.9=0.181
P.S.2.: in enchant results table can see some strange "windows" when i use 10, 11, 28, 800... scrolls for +5. This is jut my opinion - need more test for prove.
Resume: if someone ask me wort to use maphr, nano pots and etc for enchanting - i will say no. If you have 35-93 luc its just 0.5% lady shance
