Create a Roblox-style 3D model of a final evolved spirit named "Frost King" (빙설왕). Design a majestic ice deer with large crystalline antlers. Use smooth semi-transparent icy textures, not realistic but stylized. Colors should be pale blue, white, and light cyan. Add floating snowflake particles and a soft frosty mist aura. The style must be simple, clean, and optimized for Roblox, but still feel premium and collectible. Focus on a strong silhouette and a magical, cold beauty. Avoid hyper-detail or realistic surfaces.
