Create a stylized 3D isometric single boulder (game prop) matching the same League of Legends / Supervive-inspired hand-painted + cel-shaded art direction. One rock only, medium size, with a strong readable silhouette: chunky form, clear planes, slightly exaggerated bevels and edges. Use soft gradient ramp shading, crisp ambient occlusion, subtle outline accents. Surface detail: a few stylized cracks, chipped corners, light stratification hints, tiny moss patches kept subtle—no unique markings. Neutral gray with slight warm/cool variation. Consistent isometric/top-down lighting, neutral studio background, high resolution, sharp focus.
