What This Guide Helps You Do
This guide walks you through every step needed to craft the Terra Blade, one of Terraria’s strongest melee weapons before Plantera. You’ll learn where to find each component, how to farm the rare drops you need, and the exact crafting sequence to merge everything together. It’s designed for players in Hardmode who’ve defeated the Wall of Flesh and want a powerful single-target and crowd-control weapon that fires piercing green energy beams.
Requirements & Prep
Boss Progression Required:
- Wall of Flesh defeated (to enter Hardmode)
- All three mechanical bosses defeated: The Destroyer, Skeletron Prime, and The Twins
- Access to the Jungle Temple (for the Solar Tablet, though not strictly required)
Crafting Stations Needed:
- Mythril or Orichalcum Anvil (for final Terra Blade merge)
- Demon or Crimson Altar (for crafting Night’s Edge and Light’s Bane or Blood Butcherer)
- Standard Furnace and Anvil (for intermediate crafts)
Materials You’ll Gather:
- Hollowed Bars (from mechanical bosses)
- Jungle Spores and Stingers (from the Jungle)
- Hellstone and Obsidian (from the Underworld)
- Demonite or Crimtane Ore (from early Hardmode or pre-Hardmode bosses)
- Golden Keys (from the Dungeon)
- Broken Hero Swords (rare drop from Mothron)
Route Overview
The Terra Blade crafting chain is long but logical. You’re essentially building two “true” swords—True Excalibur and True Night’s Edge—then merging them. True Excalibur is straightforward: farm Hollowed Bars from mechanical bosses, craft Excalibur, then combine it with a Broken Hero Sword. True Night’s Edge is more involved because Night’s Edge itself requires four different swords merged together. Once you’ve both true swords and access to a Mythril or Orichalcum Anvil, the final merge takes seconds.
The critical bottleneck is Mothron. You’ll need two Broken Hero Swords from this enemy, and it only has a 25% drop chance. Plan to fight Mothron multiple times. Solar eclipses occur naturally with a 5% daily chance, or you can force them with a Solar Tablet from the Jungle Temple.
Step-by-Step Walkthrough
Step 1: Defeat the Three Mechanical Bosses and Collect Hollowed Bars
Your first goal is to farm Hollowed Bars from The Destroyer, Skeletron Prime, or The Twins. These bosses spawn naturally in Hardmode after you defeat the Wall of Flesh, or you can summon them using their respective summoning items. You’ll need enough Hollowed Bars to craft an Excalibur. Defeat the mechanical bosses repeatedly until you’ve got a comfortable stockpile. Each boss drops multiple bars per defeat, so you shouldn’t need to farm excessively.
Step 2: Craft Excalibur
Once you’ve got Hollowed Bars, head to a furnace and craft Excalibur. It’s straightforward—no merging required yet. Excalibur is one half of what you’ll need to create True Excalibur.
Step 3: Hunt Mothron for Broken Hero Swords
This is the longest part of the Terra Blade journey. You’ll need two Broken Hero Swords, and Mothron is your only source. Mothron spawns during solar eclipses, but only after you’ve defeated all three mechanical bosses (which you’ve already done). Solar eclipses occur naturally with a 5% chance each day, or you can trigger one immediately using a Solar Tablet from the Jungle Temple.
What to expect from Mothron: This is a flying enemy that dashes at you aggressively and spawns Baby Mothron eggs that hatch into additional enemies. The fight is genuinely difficult and requires strong gear. Bring a weapon like the Mega Shark or Amarok with a Yo-Yo Bag equipped. Use mobility and healing potions liberally. With a 25% drop rate for Broken Hero Swords, expect to fight it 4–8 times on average to get two swords. This isn’t a quick farm.
Rare Drop Alert: The 25% drop rate means you may need many attempts. Don’t get discouraged if you fight Mothron 10+ times without seeing both swords. This is normal variance.
Step 4: Gather Jungle Spores and Stingers for Blade of Grass
While farming Mothron, you can simultaneously gather materials for Night’s Edge. Head to the Jungle and collect 12 Jungle Spores and 12 Stingers. Jungle Spores glow and are easy to spot on the ground or hanging from vines—just attack or mine them. Stingers drop from Spiked Jungle Slimes and Hornets at a high rate, so you won’t struggle to collect 12. Once you’ve both, craft the Blade of Grass at an anvil. This is the first of four swords you’ll need for Night’s Edge.
Step 5: Craft the Fiery Greatsword
The Fiery Greatsword requires 20 Hellstone Bars, which you craft from Hellstone and Obsidian in a furnace. If you’re new to Terraria, check out the creator’s separate Hellstone guide for detailed farming. Once you’ve got the bars, craft the Fiery Greatsword at an anvil. This is the second sword for Night’s Edge.
Step 6: Obtain the Muramasa from the Dungeon
The Muramasa is found in Gold Chests scattered throughout the Dungeon. These chests require Golden Keys to open. You can find Golden Keys in wooden chests throughout the Dungeon or as drops from Dungeon enemies (low rate). However, if you encounter a Dungeon Slime, it’ll drop a Golden Key with 100% certainty—hunt these specifically to speed up the process. Open a Gold Chest to retrieve the Muramasa. This is the third sword for Night’s Edge.
Step 7: Craft Light’s Bane or Blood Butcherer
Your world contains either Corruption or Crimson biomes. You’ll need Light’s Bane (Corruption worlds) or Blood Butcherer (Crimson worlds). Both require 10 ore: Demonite Ore (from Corruption) or Crimtane Ore (from Crimson). These ores drop from the Eye of Cthulhu and the Eater of Worlds (Corruption) or Brain of Cthulhu (Crimson). If you haven’t defeated these early-game bosses, do so now and farm the ore, then craft the appropriate sword at an anvil. This is the fourth sword for Night’s Edge.
Step 8: Merge Four Swords into Night’s Edge
Now you’ve got Blade of Grass, Fiery Greatsword, Muramasa, and Light’s Bane or Blood Butcherer. Head to a Demon Altar or Crimson Altar and merge all four swords into the Night’s Edge. This is a single crafting action that consumes all four swords and produces Night’s Edge.
Step 9: Combine Night’s Edge with a Broken Hero Sword
Take your Night’s Edge and one of your two Broken Hero Swords from Mothron. At a Demon or Crimson Altar, merge them to create True Night’s Edge.
Step 10: Combine Excalibur with the Second Broken Hero Sword
Take your Excalibur and your second Broken Hero Sword. At a Demon or Crimson Altar, merge them to create True Excalibur.
Step 11: Final Merge at Mythril or Orichalcum Anvil
You now have True Excalibur and True Night’s Edge. Head to a Mythril or Orichalcum Anvil and merge these two swords together. The result is the Terra Blade. You’ll unlock an achievement upon your first craft. Congratulations—you now wield one of Terraria’s most powerful melee weapons before Plantera.
Builds & Loadouts
Recommended Gear for Mothron Farming
Since Mothron is the bottleneck and requires multiple fights, equip yourself properly:
- Weapon: Mega Shark or Amarok with a Yo-Yo Bag equipped
- Armor: Late-Hardmode melee or ranged armor (Mythril or Orichalcum tier minimum)
- Accessories: Hermes Boots or Cloud in a Bottle for mobility; Cloud in a Bottle is especially helpful for vertical dodging
- Consumables: Healing Potions (stack high), Ironskin Potion, Regeneration Potion, Swiftness Potion
Troubleshooting & Common Mistakes
- Mistake: Fighting Mothron before defeating all three mechanical bosses. Fix: Mothron only spawns during solar eclipses after you’ve defeated The Destroyer, Skeletron Prime, and The Twins. Confirm all three are dead before attempting a solar eclipse farm.
- Mistake: Forgetting you need TWO Broken Hero Swords. Fix: Plan ahead. You’ll need to fight Mothron multiple times. Don’t assume you’ll get both swords in one or two fights. Budget 5–10 attempts.
- Mistake: Using a Broken Hero Sword for something else. Fix: Both Broken Hero Swords are essential for the Terra Blade chain. Don’t craft them into other items. Store them safely in a chest until you’re ready to merge them.
- Mistake: Crafting Night’s Edge at the wrong altar. Fix: Use a Demon Altar or Crimson Altar, not a regular anvil. You can find these in the Underworld or Corruption/Crimson biomes.
- Mistake: Not having a Mythril or Orichalcum Anvil available. Fix: These are crafted at a Furnace using Mythril or Orichalcum Bars and Wood. Craft one before you reach the final step, or locate one in the Underworld.
- Mistake: Dying to Mothron repeatedly without progress. Fix: Bring more healing potions, use terrain to your advantage, and consider farming better gear first. Mothron is genuinely difficult; it’s okay to delay this farm if you’re struggling.
- Mistake: Confusing Hollowed Bars with Hellstone Bars. Fix: Hollowed Bars come from mechanical bosses and are used for Excalibur. Hellstone Bars are crafted from Hellstone and Obsidian and are used for Fiery Greatsword. They’re different materials.
- Mistake: Trying to craft the Terra Blade before gathering all components. Fix: You’ll need both True Excalibur and True Night’s Edge in your inventory before attempting the final merge. Gather everything first, then go to the anvil.
Advanced Tips & Time Saves
- Solar Tablet Rush: If you’ve access to the Jungle Temple (post-Plantera), grab the Solar Tablet and use it to force solar eclipses immediately instead of waiting for the 5% daily chance. This dramatically speeds up Mothron farming.
- Parallel Farming: While waiting for solar eclipses, farm Jungle Spores, Stingers, Hellstone, and Demonite/Crimtane ore simultaneously. This prevents downtime and keeps you progressing on other Terra Blade components.
- Mothron Arena Setup: Build a simple arena with platforms and walls to control the fight. Mothron dashes at you, so vertical space and escape routes are crucial. A 40–50 block tall arena with horizontal platforms works well.
- Gear Upgrade Before Mothron: If you’re struggling, farm the Mega Shark first from the Destroyer. It’s one of the best weapons for Mothron and makes the fight significantly easier.
FAQ
Q: Can I craft the Terra Blade before defeating Plantera?
A: Yes. The Terra Blade requires no Plantera drops. However, it’s an excellent weapon to use against Plantera once you’ve got it.
Q: What does the Terra Blade do?
A: It’s a melee weapon that shoots a green beam of energy. The beam pierces through enemies and can hit up to three targets. It has high base damage and is one of Terraria’s strongest weapons before Plantera.
Q: How many Broken Hero Swords do I need?
A: Two. One for True Excalibur and one for True Night’s Edge. Both are required for the final Terra Blade merge.
Q: Can I get Broken Hero Swords from anywhere other than Mothron?
A: No. Mothron is the only source. That’s why the farm is the bottleneck of the entire chain.
Q: Do I need to defeat Plantera to get the Terra Blade?
A: No. Plantera isn’t required. However, you do need to defeat all three mechanical bosses and farm Mothron during solar eclipses.
Q: What’s the fastest route if I’m speed-running this?
A: Defeat mechanical bosses for Hollowed Bars, craft Excalibur, then immediately start farming Mothron. While waiting for solar eclipses, gather all other components (Jungle Spores, Stingers, Hellstone, Demonite/Crimtane ore, and the Muramasa). This minimizes idle time.
Quick Reference Card (Screenshot This)
- Goal: Craft Terra Blade at Mythril/Orichalcum Anvil
- Requirements: All three mechanical bosses defeated; Mothron farmable
