Design an icon for a D&D spell that features a spectral, glowing, elongated magical construct emanating from a caster's aura. This construct should have a smooth, curved form resembling a wand or staff, symbolizing power, vitality, and force. At the base of the construct, incorporate two symmetrical, round magical orbs or spheres side by side. Surround the image with intricate arcane runes and mystical energies to emphasize its magical nature. The overall design should be bold and evocative, subtly hinting at enhancement and strength, while remaining tasteful and appropriate for all audiences.
