Herb picking, mining and skin picking are the three major occupations to obtain herbs/minerals/skin from wild or monsters.

Herbal washing skills required for alchemy/inscription.

Forging/jewelry/engineering needs the skills of ore washing of materials.

Making leather requires the skill of leather punching.

Tailor, this is the skill of not punching from monsters.

PVP is short of good projects, but the replacement without learning to mine is about 2wg slower than ours, and you didn't spend much g after learning to mine.

And learning professional skills is still considered after 80. You can't go to the mine of advanced map until you are 28 years old.
