Gunblade

At one point. An artificer had an idea. Guns... blades..  why not both? And thus, the Gunblade was born. The Gunblade Artificer is a master of innovation and elemental warfare, combining the precision of firearms with the versatility of a blade. These ingenious tinkerers channel their arcane knowledge to craft unique fusion weapons capable of discharging fire, cold, and lightning energy. By infusing their spells directly into their Gunblade, they unleash devastating elemental strikes, cleaving through foes with fiery explosions, freezing winds, or crackling bolts of electricity.
