The Adventurer is all about speed. The Adventurer's attack speed is the highest of all the jobs and so the Adventurer deals a lot of damage quickly. Adventurers are melee, so they can only hit enemies in the front of the pack.
You can change other heroes to this class by building the Adventurer's Pub.
Tipp: Level your Adventurer up to lvl 13. With the Scavange II skill you can farm wood and metal faster than normal - even at low level floors. I prefer 3 Adventurers lvl 13+ with full set but WITHOUT weapons. It is important not to wear weapons because you earn resources with each strike. If you wear no weapon, you can strike more often from this it follows that you earn more ressources.
Lvl 10 without weapons: 627 wood // 245 metal
Lvl 10 with weapons: 549 wood // 129 metal
