Wind Archer (Wind Breaker) is one of the five jobs offered to the Cygnus Knights. This job is essentially an Archer that uses Nature based attacks. Wind Archers also have the ability to summon Storm, a spirit that aids the player in battle.
At level 10, players have the opportunity to become a Wind Archer. They must speak to the tactician Neinheart in Ereve. Afterwards, just speak to Irena on the left part of the same map and she will advance you to a Wind Archer.
