create a minecraft item that has the following description: 'Create a custom weapon called Soulbone, a base weapon that can be wielded by any version of Sans across the multiverse. The weapon is a large, magically-enhanced bone sharpened into a spear-like or jagged shape. It's infused with soul energy, glowing faintly in colors that reflect the wielder's AU in my case this will be mostly black and some dark blue parts. It should feel raw, primal, and efficient — not elegant, but undeniably powerful. Attacks deal physical and magic damage, and the weapon can channel small bursts of magic, like bone projectiles or soul-piercing stabs. Include clean bone textures, a slight aura effect, and a short lore blurb explaining that the Soulbone is the foundation of every Sans's combat style, forged from their innate magic.'
