The Muramasa attacking a Target Dummy.

The Muramasa is a blue broadsword that is found in the Dungeon's Locked Gold Chests or in Golden Lock Boxes, both of which are opened via a Golden Key. The Muramasa has a slightly longer reach than the Phaseblade and has a fast attack speed. It is also worth mentioning that it is an autoswing sword, not many of which can be found during Pre-hardmode. It also emits a small amount of light when swung.

Its best modifier is Legendary.

  • This weapon is useful early on when dealing with large groups of enemies due to its autoswing.
  • It may not be the most powerful of weapons but can be effective while running for killing slimes, knocking back flying enemies, clearing Thorny bushes, cutting away weeds and harvesting plants.
  • The fast attack speed of the Muramasa can be enhanced even further by equipping Feral Claws and a full set of Shadow armor, along with the Well Fed and Tipsy buffs, making it a very viable weapon up until Hardmode.
  • It swings even faster than the Night's Edge, but its relatively weak knockback makes it a poor choice against most enemies if not backed up by melee speed enhancements.
  • Its long reach and fast speed make it effective for battling flying enemies like Demon Eyes, Cave Bats, and Demons.


  • Muramasa is named after a famous swordsmith of the same name who lived in 16th century Japan.
    • The sword that he made is also called the Muramasa.
  • Other Muramasa swords also appear in many other games.
  • The Muramasa is one of the few pre-Hardmode melee weapons that has autoswing.
  • Muramasa was the first weapon in the game to be the most powerful. That lasted until its damage and knockback were reduced and the ability to equip more than one pair of Feral Claws was removed, long before the 1.1 update when Hardmode was introduced. Prior to these updates, its high attack speed combined with the knockback it caused made it nearly impossible for enemies in front of the player to come close.
  • In the 1.4.1 patchnotes, the phrase "How ya doin' Muramasa?" follows the header for the weapon's section. This is a reference to a video of the same name by youtuber Hectique, which criticized the weapon's lackluster adjustment in
