The Primeval Blade (also known as Aeon Blade in the SNES/PS version) is Crono's ninth-level weapon. It has an attack power of 70. It can be traded for at the Ioka Village Hut for 3 Fangs and 3 Horns and/or charmed from Megasaur. In-game, the blade of the weapon's sprite is shared with the Silver Sword, Thunder Blade, Onimaru, Rainbow and both of Slash's weapons. However, its slashing trail is that of a twin sparks forming a distorted lighting bolt shape (both colored yellow-orange), an effect shared by the in-game versions of both the Yaksha Blade and Zanmato.
