Well don't unpack if you want to know the indexes, because as already mentioned above, you can find the indexes by going to the CRC Folder in bin, then share and then skill and open the corresponding file. You have to search for Index,<number here> and yes, You need the comma. Although if you already decided to unpack it, I would give it a try and use good ol' csv editing :D I find it much more comfortable although some say it makes more crashes.
Now about editing, what you are looking for is that when you find the skill, you see specific lines, for example this:
Code:
1,NO_CANCEL,255,10000,1000,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
2,NO_CANCEL,255,10001,500,0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,
3,NO_CANCEL,255,16,570,0,0,0,0,0,0,0,0,0,0,0,0,0,0,3,
4,NO_CANCEL,255,25,3,0,0,0,3000006,44,448,0,289,0,0,0,2014,1,3000,4,
5,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,
6,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,6,
7,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,7,
8,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,8,
9,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9,
10,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,10,
11,NO_CANCEL,255,10000,1000,0,0,0,0,0,0,0,0,0,0,0,0,0,0,11,
12,NO_CANCEL,255,10001,500,0,0,0,0,0,0,0,0,0,0,0,0,0,0,12,
13,NO_CANCEL,255,16,570,0,0,0,0,0,0,0,0,0,0,0,0,0,0,13,
14,NO_CANCEL,255,25,3,0,0,0,3000006,44,448,0,376,0,0,0,2014,1,3000,14,
Every 10 lines after 1 is a new skill, so 11 or 1 is level one, 22 or 11 is level two (can't remember where it starts). So you must edit the 3rd value after the NO_CANCEL Line (that goes same for every skill-hack) and I edit whichever value is over 100 (3rd value of course)
So the cast time done for level 1 would look like this:
Code:
1,NO_CANCEL,255,10000,[color=red]0000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,1,
2,NO_CANCEL,255,10001,[color=red]000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,2,
3,NO_CANCEL,255,16,[color=red]000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,3,
4,NO_CANCEL,255,25,3,0,0,0,3000006,44,448,0,289,0,0,0,2014,1,3000,4,
5,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,
6,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,6,
7,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,7,
8,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,8,
9,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,9,
10,ACTION,255,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,10,
11,NO_CANCEL,255,10000,[color=red]0000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,11,
12,NO_CANCEL,255,10001,[color=red]000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,12,
13,NO_CANCEL,255,16,[color=red]000[/color],0,0,0,0,0,0,0,0,0,0,0,0,0,0,13,
14,NO_CANCEL,255,25,3,0,0,0,3000006,44,448,0,376,0,0,0,2014,1,3000,14,
Sometimes there are also ACTION lines with cast times, You may edit them as well as long as they have a logical cast time value. Now I'm not sure if only editing the cast time would work, so I'll show editing the cooldown too. Basically, the cooldown hack does not work like people imagine it to, but I think it makes skill spamming possible. So once You're done with level 10 cast time, move on to cooldown. Scroll down a bit and You will see something like this:
Code:
LevelIndex,SPCostLevelUp,PCLevel,MaxOption,OptionIndex,OptionCode,OptionValue,MaxRequire,ReqIndex,Index,Level,CastTick,CoolTick,StartComboIndex,EndComboIndex,ResourceHP,ResourceMP,ResourceItemCode,ResourceItemCount

The value of 2700 is something called Cast Tick, which I have not encountered with the incar magician, so you should probably edit that one too. Now the number after Cast Tick is the Cool Tick, change all the level values of the cool tick & cast tick and You're done!
