If your new to mining Mount Z. I'd recommend White Mage Subjob if not using it as your main job while mining.
Setup your moghouse for Mog enhancement:Experience
(death is quite common result of extended mining in dangerous area and it can be frustrating)
Reraise is your friend here.
Purchase the following gearups as soon as possible.
Field/Worker Tunic, Field/Worker Gloves, Field/Worker Boots
Skulker Mantle - (enhances Sneak and Invisible) Doubling the Time your sneak and invisible stay up. a Very Useful item.
It may take weeks before you hit Khroma Ores.. You might never hit Khroma Ore. But your gaining other items while your searching for the big payoff..
Focus on crafts that can turn the other items on the list into gil.
Alchemy, Smithing, GoldSmithing.. woodworking (if your going with fishing pole plan.)
If your able to convert the adaman ores into ingots and convert the moblin gear into ingots. moblin masks and armor into leather or glass fibers.
you can convert the glass fibers into fishing poles. and all the other trash into steel ingots and bullets.
Everytime you move the Raw Product up the Craft Chain into more useful items.
Depends on Server Economy though so check with ffxiah on your server.. for niche markets.
If you can turn the 50 or so moblin masks into glass fibers and fishing rods
Moblin Mask - Alchemy (29) Desynth.
Troll Brass Sheets Dont Sell very well but the clubs you can make from them do sell very nicely if your a high level smith.
demon horn. bone chip wind crystal makes demon arrowheads - nice if your ranger with scavange. if not its at least 4-5k each horn on ah.. and they sell very quickly.
as frustrating as this area is to mine.. There is still good money here even with pick axe costs and deaths..
you got 5 adamant ores.. somedays i mine with no adamant ores.. stacks of flint stones and sulfur.. but even with bad days. travel expenses and pick axe expenses. i wind up with a full goblin bag of loot to dump on ah and sometimes its good to get away from the xp party grind and ls to do your own thing.
To often in this game you get caught up in helping other people and powerleveling.. that you lose your Greedalox abilitys.
Unlearn all that party junk n friends who use you for thier self-advancement...
This is about You and your trusty shovel and your inner GREEDALOX!
Best of Luck
