Tsaisi
this snake-like creature was genetically created by the Yuuzhan Vong. Shorter and narrower than an amphistaff, the tsaisi was worn coiled around the arm as a sign of a Yuuzhan Vong's position within the military. The tsaisi was of the same species as the amphistaff, but was much more delicate and more difficult to wield in battle. That made its appearance very rare, and the wearer was a warrior of incredible skill in both battle and command.
