This +1 striking longspear of polished white bone features a tip of layered reptilian scales, compressed to form a sharp edge. Akki crafted this spear herself after she and her allies tangled with a hydra plaguing the marshes outside Aelyosos. She pressed the scales of the creature down into a spearpoint mostly through sheer stubbornness, granting it a unique ability.
