MapleStory Chaos: Profession Recipe Guide

Hmmmm:
- Alchemy -Premium Giant Potion- sounds fun, however, the recipe expires after 1 day, so it's quite useless imo... :/
- Blacksmith -Premium Android- is ok
- Jewel crafting -Dark Angelic Blessing- is ok

Question:
So if you can use Mining to get all the ores and Jeweling to make items to lvlup Jeweling to lvl10, all for making the Dark Angelic Ring, why are people stocking up on ores right now?

Because all the professions share one fatigue bar, and with more fatigue to level up jewel crafting, you'll get level 4/10 faster.
