A cunning and dangerous goblin engineer ready for combat, standing in a shadowy workshop filled with explosives, mechanical traps, and tinkering tools. He wears a patched leather apron with soot stains and has belts filled with alchemical vials and small bombs strapped across his chest. His hands are dirty, gripping a wrench in one hand and a small lit bomb in the other. His eyes gleam with intelligence and mischief, his skin is a sickly green, and his wiry frame exudes agility. The background is dimly lit, with faint sparks and glowing runes on the workshop walls, hinting at his inventive expertise. A sense of controlled chaos surrounds him.
