Harvest=> GiddeusGiddeus many of the spots are in the same areas as Birdmen that drop the Kaz Key.
You can harvest in west saruta but they spots seem really spread out :( what you can expect? Mugworts, cotton etc 1 stack mugwort = 60k
Lvl 30ish
Mining there is ALOT of compitition doing this,
Zeruhn Mines(10), Yughott Grotto(30), Palborough(depends on area 10-30), Gusgen(not enough pops to really make it worth it, 40) You can also kill worms for ore drops.Gusta, Ron, Korro, Altepa etc I suggest killing easier worms so you can get more and lose less hp(or none at all)
Lumber
Ghelsba Outpost - the first level (very popular area) lvl10
East Ronfaure - near the castle and also in what I refer to as "Sheepland" located somewhat near the Ranguemont pass. Also down near Ron Ps tomb are sites. They are really spread out and because of that few people collect lumber here.(lvl 10)
Buburimoooooo- all along the coast (where all the trees & crawlers are) this are is profitable you can get rosewood (5k) and ebony logs here as well as hunting crawlers and bull dhamels.(lvl 25-30s)
Excavating Bones (My fav)
Tahrongi Canyon- 3 spots are set in a triangular pattern around the crag mea. 1 is near maze of shakrami enterance, another is off to the left of Meraphatad Mts by the Stone Monument (selbina clay quest) the 3rd halfway between the crag and zone to buburimooooo.the 4th is down int hat maze of mountains that leads to saruta zone.(lvl15 min but reccomend 20 if you plan on also farming dhamels)
Maze of Shakrami I dont much like excavating here because you have to wander around too much however if you kill the skelatons and scorpians along the way you can make up for such few points. (lvl 40s)keep in mind the spot you are excavating might be important to a fledgling DRG.
Korroloka Tunnel - I have yet to find a spot to excavate here, sorry.
Digging
I'm sorry but this never sounded financially worthwhile to me. My gil has creases I pinch it so hard. even if you farm the plants to make the choco dig you still have to pay for a choco...so say that choco is 90 gil and you have 5 plants and dig nothing up (as usually happens) in the amount of time it took to get the choco and dig you couldve made at the least 1k killing stuff.However, there may be people out there who knopw tricks to making this financialy feasable and I welcome their advice.
