Movie-level game CG rendering, dark fantasy style, hyper-realistic material representation, 8K resolution, HDR high dynamic range, global illumination, subsurface scattering. A mysterious spirit cloaked in a frost cape, the cape made of frozen ice crystals and energy, with a surface covered in cracks and icy textures, giving a semi-transparent icy blue feel. Under the hood is a mask made of dark energy and ice crystals, with sharp icy blue light emanating from its eyes. The edges of the cloak disperse cold blue smoke and ice particles, fusing with the main body. Blue energy patterns pulse like lightning, with dynamic blur and glow effects at the edges, while the icy crystal surfaces reflect sharp light, with delicate refraction and scattering. The background features deep gray mist, filled with blue smoke and ice particles, with light from above penetrating the mist to create strong rim light, making the icy blue energy prominent in the darkness, creating a mysterious and dangerous atmosphere. The roughness and reflectivity of the icy surface are precisely controlled, without any plastic feel, with details rich enough to capture the cracks in the ice crystals and energy patterns, while dynamic blur enhances the sense of smoke flow, delivering strong visual impact, full of epic and oppressive feelings.
