Tyrant Yharim's Ultisword

The Tyrant Yharim's Ultisword is a craftable Hardmode broadsword that autoswings. It will shoot out a red blade which homes in on enemies and gradually slows to a stop, similar to the blades created by Pumpking. Upon hitting an enemy with the sword itself, it will have a 50% chance to give the Tyrant's Fury buff to the player, increasing melee damage by 30% and melee critical hit chance by 10% for a short period of time. The sword also inflicts the On Fire! and Venom debuffs on enemy hits.
