Thanks for the tip!
I also found a little section myself where you can find a great spot to gain 99 yellow liquids and water crystals in a very short time!
In the Henne Mines, there is 2 small sections that control the gates inside a 4-way intersection, and when you hit the switch inside these rooms, Jellys fall from the ceiling. In the second section, FAR more Jellys drop and they all love to use the divide move. I got up to chain 230 in just 5 visits to this room, lol. My gambits and characters were set-up just so that Fran (my "paladin char") was always in and had a char casting decoy on her before hitting the switch. Protect helps too, but not needed if your set-up right. Equip the best shield available to you, and the gauntlets accessory. If you have the LP available, make sure to get as many Sheild Block augments as possible. For your other 2 characters, all you gotta do is have them constantly cast AoE magics, and watch the carnage and items come rolling in!
Yellow liquids sell for just around 550 , you can make 50k just in that before you gotta teleport outta there to sell em all. Also they on rare occasions (also with a Monograph's help I believe) they drop Float motes and Teleport shards, so you wont lose any shards for the constant teleporting you'll be doing.
So far this has been the fastest way of making money i've seen, I'm sure there'll be better spots later on, but I thought I would share this one awesome spot with you all, happy hunting! ^^
Edit: Water magicite pieces are the other drop name, not crystals, also when your charachters are higher lvl, try not to one-shot them otherwise you'll only get about 15-17 kills per visit, lol noticed when I killed em too quick I get less kills per time, try to spread out the time you take to get the maximum benefit of the dropping ones and the ones that choose to divide.
And another note, if possible, have your characters protected against Confusion, one well placed Phantasmal gaze will have you hurten, you have been warned, lol. ^^
