How to Get the Muramasa in Terraria — Step by Step
Defeat Skeletron for safe Dungeon access
The Muramasa is inside the Dungeon, which is guarded by Dungeon Guardians that instakill players until Skeletron is defeated. Defeat Skeletron at the Dungeon entrance at night — wait for it to spawn naturally or use a Suspicious Looking Skull (30 Bones + Dungeon entrance at night). After Skeletron is defeated, the Dungeon is safe to explore at any depth.
💀 Defeat Skeletron first — Dungeon Guardians block access to chests below surface thresholdFarm Golden Keys from Dungeon enemies
Golden Keys drop from ANY Dungeon enemy at approximately a 1% chance — Skeletons, Skeleton Archers, Angry Bones, Armored Skeletons, Dungeon Slimes, Blazing Wheels, etc. Kill everything you encounter in the Dungeon. Expect to need 5-15 Dungeon enemy kills per key on average. A Battle Potion + Water Candle speeds up key accumulation.
🗝️ Golden Keys: ~1% from any Dungeon enemy — farm naturally while exploringExplore all Dungeon rooms and branches for locked chests
Locked Gold Chests (identifiable by their golden lock visible on the chest icon) are found throughout the Dungeon in rooms and corridors. Explore all branches, especially going as deep as possible. The Muramasa appears in 1-2 of these locked chests per world — explore systematically, using the minimap to track visited rooms.
🏰 Locked Gold Chests have a visible lock icon — explore all branches on your minimapOpen locked chests with Golden Keys
Once you have a Golden Key in inventory, approach a locked Gold Chest and interact with it — the key is automatically consumed to unlock it. Inside can be: Muramasa, Cobalt Shield, Magic Missile, Aqua Scepter, Blue Moon Flail, Valor Yo-yo, Handgun, Spiky Ball trap, Dungeon-specific items. Each key opens one chest.
🔓 Interact with locked chest + Golden Key in inventory = auto-consumed, chest opensIdentify the Muramasa in the chest contents
The Muramasa appears as a blue sword icon inside the chest. If you do not get it on the first locked chest, continue exploring and farming more Golden Keys. The Muramasa spawns in at least 1 chest per world — if you have opened every accessible locked chest without finding it, try using Spelunker Potions to find any missed chests.
🗡️ Blue sword icon in chest = Muramasa — Spelunker Potion reveals missed chestsUse the Muramasa standalone or in the Night’s Edge
The Muramasa is a powerful pre-HM melee weapon on its own — fast attack speed, 27 damage, auto-swing. More importantly, it is an ingredient in the Night’s Edge recipe at a Demon or Crimson Altar: Muramasa + Light’s Bane/Blood Butcherer + Blade of Grass + Fiery Greatsword = Night’s Edge. The Night’s Edge chain eventually leads to the Terra Blade and Zenith.
⚔️ Muramasa → Night’s Edge → True Night’s Edge → Terra Blade → Zenith crafting chainPro Tips
Golden Keys are used for ALL locked Gold Chests in the Dungeon, not just the Muramasa chest. If you find locked chests containing non-Muramasa items, those keys are still well spent — the other items (Cobalt Shield, Handgun, etc.) are all excellent.
Use Spelunker Potions when searching for missed locked chests — the golden glow they emit highlights both regular and locked chests, making it impossible to accidentally miss one while exploring.
The Cobalt Shield (also in locked Dungeon chests) is an excellent accessory providing knockback immunity — if you find it before the Muramasa, use it and keep hunting for the Muramasa.
In Hardmode, the Dungeon gains new locked chests (Biome Chests) requiring different keys. These post-Plantera chests contain powerful Hardmode weapons. The Golden Key system remains relevant throughout the game.
If you play on a new world and want the Muramasa quickly: bring a Water Candle from a previous world and use Battle Potions immediately upon entering — this accelerates both key and enemy loot acquisition.
The Muramasa is one of the most important pre-HM drops due to its role in the Night’s Edge crafting chain — a chain that ultimately leads to the Zenith. As a weapon it is already excellent in its own right, with the fastest attack speed of any pre-HM sword. The Golden Key farming method means finding it is partially a grind, but any Dungeon enemy can drop keys, making the process feel natural during normal Dungeon exploration.
