>chan at my spear
You channel at an elven infantry spear.
You make a horribly poor attempt! Success!
Visible wisps of essence dance across the surface of the elven infantry spear as you chant quietly, your sure gestures guiding them to slowly coalesce into a pair of small softly glowing runic symbols. The two lone runes flicker momentarily, the intensity of their glow increasing as their form sharpens into crisp, clean edges. Suddenly, the symbols erupt in a cascade of tiny prismatic motes of light, encompassing the spear to form a shimmering layer over its surface. Slowly, the radiant shell sinks into the spear, leaving behind a faint, fading aura.
