Yea the bug its simple, the skill edit potions isnt necessary at all.
Basically you can upgrade any skill if you have enough SP for afford the required SP's for the highest level of that skill.
For those like me who can't read well the KingLi's engrish (no ofense XD), here you are an small explanation:
The bug that KingLi mentioned works in 2 parts, first you delevel any skill to lv 0 (MUST be to level 0), so you get back some SP's (or all if you use the skill potion from Item Mall). Then you have to edit your skill on the skilldata files of your media, deleting all the previous skills and leaving only the max level (or the max level you can make with your current mastery) of that skill that you downgraded to 0. Once only that line is there, you have to change the level from x to 1, and import it back to the Media.pk2.
What does it do?
The client recognizes as level 1 the skill that you have edited, and send the add skill packet to the server, with the high level instead of the real level 1. Due to a fail of security on the server, it accepts it and the skill is upgraded to the max (or just the level of the skill that you used on your skilldata). Some facts:
1. The server doesn't check for older levels of that skill, thats why this bug works (if you are enough clever with this you can find also how to fix it XD)
2. When you upgrade the skill from 0 to "1", you spend the same amount of SP as it costs as high level, thats where you can find also where is the fail of the server security.
Yeah, I said I was going to explain it very well but my english isn't very good after all XD
Sorry for that. Hope my post solves some doubts here ^^
