Where's a good place to gather LP??

I believe pots are found in the subterra

the best way to gather LP fast is equipping an accesory that doubles your lp i forgot the name and then go to the EstersandXD just beat the crap out of some wolves and cockatrices they give you 1 lp but you can beat them with one blow

Gold Amulet doubles LP

Embroidered Tipped doubles EXP

theres a pack of werewolves (in two areas in a row) just outside of golmore jungle near a save crystal. Each one gives 2LP and there are 5 in each area, with gold ammy, its 40Lp in two areas ( I HATE ZUs: stupid flying things...) And A huge pack of balgoys (giant owls)
in the lower area.

Bagolys drop "Bent Staff" at $1,200 gil a pop

Basically what ValiantKnight said with the marks that get harder as the game goes along, they tend to dish out big LP if you ahven't beaten them yet. Same with the Optional Hidden Esper battles as I think Zodiark, Chaos, and Ultima gave out some mega-LP.
