The Legend of Acrius is a high-detail, ornate shotgun with a futuristic and slightly weathered appearance, featuring a sleek, angular design with intricate engravings along its barrel and stock. Its primary body is constructed from a dark, metallic material with a matte finish, accented by glowing blue energy lines that pulse faintly, indicating its powerful energy-based ammunition. The weapon's proportions are balanced, with a compact yet robust frame, and it includes a distinctive, wide muzzle that flares slightly at the end, enhancing its menacing presence.
