I hit 55 recently, and while I wait on some friends to catch up for Genkai 2, I've decided to do some farming and set aside some gil for the future. I'm just looking for ideas to farm effectively since the places I'm going to are starting to get either old or overcamped. Here's a list of some of the ones I've been using, feel free to add your own.
Sarutabaruta- crawler silk, beehive chips (lvl 15+)
Tahrongi Canyon- wind clusters during wind weather, crawler silk, beehive chips (lvl 35+)
La Theine Plateau- wind clusters, ram skins/horns (lvl 35+)
Valkurm dunes- lizards for lizard skins (lvl 30+)
Jugner Forrest- Tiger hides, mistletoe/puffbals from trees, beastcoins (lvl 40+)
Rolanberry- gobbues for treecuttings and moss, crawler silk, beehive chips, goblins for various chain pieces (lvl 50+)
Passhow marshes- marlboro vines and dodge headbands, gobbue moss and treecuttings, crawler silk (lvl 40+)
These are some of my favorite spots, and on a decent day I usually average 15-20k/hr, sometimes close to 30k/hr if my buddy with high leathercraft synths ram and tiger leather with me. If anyone has any other suggestions or favorite spots you don't mind sharing, please let me know, because I'm looking for some new stomping grounds.
