Create a detailed 3D model of a short steel spear with a polished blade and a matte shaft. Carve a spiraling band of glowing runes around the shaft, with subtle markers at the beginning and end of the spiral. Finish the pommel as a simple steel sphere. Apply realistic metal materials plus emissive effects for the runes.

Use dark cool-gray carbon steel for the shaft with a micro-pitting and random abrasion normal map for subtle roughness. Roughness 0.75–0.85 overall, 0.60 in grip; add 0.1–0.2 noise and micro-scratch detail in the Normal map; Metallic 1.0. Engrave a 4.5-turn spiral of runes (1 mm deep, 6 mm wide) from the shaft collar to spearhead. Emissive map: ice-blue glow pulsing 20–40% intensity with a 2 mm white halo. Specular 0.9 on runes. Height/Normal maps capture 1 mm etch depth, 0.5 mm ridges, and 1 mm fillet grooves. Texture the spearhead in bright silvery steel. Roughness 0.15–0.25 for mirror-like reflectivity; overlay a 5% opacity micro-scratch Normal map; Metallic 1.0. AO map emphasizes shadows in rune grooves, fillet channels, and grip transitions to maximize depth.
