The Thunder Blade (also known as Bolt Sword in the SNES/PS version) is Crono's fifth-level weapon. It has an attack power of 25. It can be found in a chest at the Abandoned Sewers and/or the Derelict Factory in a chest. In-game, the sword's sprite via its blade is the same as the Silver Sword, Primeval Blade, Onimaru, Rainbow and Slash's two swords (silver white), though the slashing trail being colored yellow-ish white (akin to the Light element) is the main difference between the Silver Sword and Thunder Blade visual-wise.
