The Shuriken of Serpents were weapons of an unknown origin. The Mantis indicated a possible origin in the Ivory Kingdoms. They were used by members of the Unicorn Clan, who claimed that they were originally taken from the bodies of failed assassins sent to kill Unicorn Clan leaders. When thrown they would turn from regular, if strange looking, shuriken into a tangled mass of snakes that would bite its target. The shuriken could also sometimes bounce to other adjacent targets, before finally shatters when hitting the ground.
