Rend of the Ninth Splinter

This +3 longsword is forged from a dark alloy that never reflects the same shape twice. Its edge ripples like broken glass submerged in water, and the fuller of the blade holds a slow-moving storm of tiny colored sparks. The guard is shaped like a cracked crown, and the pommel is a faceted crystal that clicks softly as if rolling unseen dice. When drawn, the sword sheds a halo of shifting afterimages, making every swing look a half-beat out of sync with reality.
