Alot of people skill up on this as substitute to Grape juice. But on my server (Carbuncle) fire crystals can go up to 7k a stack while Dark is always about 3-4k. SO doing the maths Grape juice synth might be cheaper to do... hmm....
Though this does have 2 extra lvls cap. But then again you can skill up on grape juice till you can't and switch
I think the cap for these is lower than 52, though I don't know where it is.
After I hit 51, I tried these out just because they looked like a cheap way to get up to 52. I did an entire stack of these with advanced synthesis on and I didn't get a single bit of skill.
Luckily they sold for about 120 each to an NPC, so I'm only out the fire crystals.
Probably because you used advanced synthesis. If you're only one level under cap (or as muc as three levels under cap), you'll get more skillups if you don't use any synth support.
To make Bataquiche you need to have a batagreen saut. Since batagreen saut. is not sold by any merchants, if the Guild point item for the day is Bataquiche you will see a lot of people making the sautee then the Bataquiche for there guild points/profit.
