What are the occupations of dwarves and orcs in western fantasy novel?

Dwarves and orcs are generally warriors.

Dwarves are a forgotten race underground. Because they live a down-to-earth life all the year round, they have a good system and strength.

Orcs are the evolutionary race of hunted animals, and generally have wild attack power and good physical strength.

Alchemists can make some drugs and weapons, just like the old gentleman in our journey to the west.
