The Sculptor

From the introduction:

A class of artistry and battle.

As the orc war chief raises his enormous greataxe, the unarmed dwarf reaches her hands in front of her, seemingly grasping the air. A blue, crackling energy extends from her hands, and she quickly shapes the raw power, forming it into an enormous hammer that must be at least her size. The orc, confused, hesitates; the dwarf doesn’t, raising the larger than life hammer above her head and charging her befuddled foe.
