The Fiery Greatsword is a Hellstone weapon that has a very slow swing speed and has the second to longest reach and damage of all melee weapons in Terraria. It emits light in the form of fire particles when swung, which can make it useful when scouting caves and scanning for ore through walls. It has a 50% chance of setting enemies on fire, slowly reducing their health over time (this effect only lasts for a few seconds).
