Masters of the gunblade, Gunbreakers are warriors who blend mechanical innovation with martial excellence. They channel aether through customized weapons to unleash explosive power on the battlefield. Once protectors of ancient royal lines, modern Gunbreakers serve as mercenaries, guardians, and champions of the weak—wielding technology once lost to time.

Gunbreakers fight with precision and ferocity, combining close-quarters combat with bursts of magical ammunition. Through rigorous training, they learn to charge and expend Munitions to fuel their techniques—empowering each strike with deadly bursts of energy.

Whether as disciplined tacticians or daring frontliners, Gunbreakers exemplify adaptability and endurance. Their strength lies not only in steel and powder, but in their mastery of timing, focus, and unrelenting resolve.

Art of the Gunblade

Each Gunbreaker trains to master both the blade and the trigger. They are living weapons—bridging the divide between soldier and spellcaster, tradition and innovation. Every movement, every strike, is an orchestration of gunpowder, willpower, and honed instinct.

Their creed is simple: To stand unbroken. To guard the light. To burn bright even when the world fades.
