Extract magical dusts, essences and shards for use to enchant various attributes, powers, and properties to all sorts of equipable items. Enchanters can also make wands, as well as oils that can be applied to weapons providing a temporary buff. The disenchanting ability available to all enchanters could be considered the "gathering complement" to enchanting.
Engineer mechanical devices, explosives, goggles, and trinkets, such as grenades, explosive sheep, mechanical pets. Usually these are crafted with metal, minerals, and stone. Most engineering products can only be used by engineers. Engineers can specialize as Goblin or Gnomish engineers.

Fishermen will now occasionally fish up creatures that are far to large to be subdued by a simple fishing rod, as well as great treasures buried beneath the sea. Both of these will reward considerably more than the average catch.
