How to Get Mythril in Terraria — Step by Step
Defeat the Wall of Flesh and get the Pwnhammer
Mythril only spawns in Hardmode. Defeat the Wall of Flesh in the Underworld using a Guide Voodoo Doll as a summon item. It drops the Pwnhammer — the only tool that can break Demon/Crimson Altars and generate Hardmode ore veins.
🔥 Wall of Flesh drops the Pwnhammer — required to break Altars and generate MythrilSmash the 2nd Demon or Crimson Altar
The 1st Altar smash generates Cobalt or Palladium. The 2nd Altar smash generates Mythril or Orichalcum. Hit an Altar with the Pwnhammer to smash it — the ore appears somewhere underground. Each additional smash cycles through the three tier tiers again. Whether you get Mythril or Orichalcum depends on your world seed.
🔨 2nd Altar smash = Mythril (or Orichalcum) ore appears undergroundGet a Cobalt or Palladium Pickaxe first
Mythril requires a Tier 1 Hardmode pickaxe (Cobalt or Palladium) to mine. Craft one from the Cobalt/Palladium Ore generated by your 1st Altar smash. Cobalt Pickaxe: 12 Cobalt Bars at Iron Anvil. Palladium Pickaxe: 12 Palladium Bars at Iron Anvil. Either works for mining Mythril.
⛏️ Cobalt/Palladium Pickaxe required first — craft from Tier 1 ore at Iron AnvilExplore underground for Mythril veins
Mythril Ore appears as silver-blue glowing blobs in the Underground and Cavern layers. Explore deep cave systems — Mythril is more common in the Cavern layer (deeper underground). Use a Spelunker Potion to highlight all nearby ore with a golden glow for much faster detection.
🗺️ Spelunker Potion highlights Mythril with gold glow — brew before any major mining runSmelt Mythril Ore into Bars at a Furnace
4 Mythril Ore smelts into 1 Mythril Bar at any Furnace (Iron Furnace, Hellforge, or Adamantite Forge). You need 10 bars to craft the Mythril Anvil and many more for armor/weapons. A full Mythril Armor set requires around 65 bars — expect to mine for 15-30 minutes with a Spelunker Potion active.
🔥 4 Mythril Ore = 1 Bar at any Furnace — 10 bars = Mythril Anvil (priority craft)Craft the Mythril Anvil — top priority first craft
With just 10 Mythril Bars, craft the Mythril Anvil at an Iron Anvil. This is the single most important Mythril craft — it unlocks nearly all Hardmode weapon, armor, and tool recipes. Place it in your main crafting area. If you got Orichalcum instead of Mythril, craft an Orichalcum Anvil from 12 Orichalcum Bars — functionally identical.
🔨 Mythril Anvil (10 bars) = top priority — unlocks all Tier 2+ Hardmode craftingPro Tips
Smashing Altars also corrupts a random surface tile each time — smash strategically in areas where biome spread damage is acceptable, not near your base.
The Mythril Anvil and Orichalcum Anvil are functionally identical — they enable the same recipes. Whether you get Mythril or Orichalcum is world-dependent and does not affect progression.
After crafting the Mythril Anvil, use remaining Mythril Bars for Mythril Armor (strong early Hardmode set), the Mythril Drill (better pickaxe), or Mythril Chainsaw (great tree/wood farming tool).
Ore veins of all three Hardmode tiers exist underground simultaneously — a thorough Spelunker Potion mining run can yield Cobalt, Mythril, and Adamantite in a single session.
The Pickaxe Axe (crafted from Hallowed Bars + Mechanical Boss materials at Mythril Anvil) is a major upgrade over the Mythril Drill. Craft it as a mid-term goal after getting the Mythril Anvil.
Mythril is a bridge ore — the Mythril Anvil crafted from 10 bars is more valuable than any Mythril weapon or armor piece. It is the gateway to all of mid-Hardmode crafting. Mine enough for the Anvil first (10 bars), then continue for armor/weapons as desired. Whether your world has Mythril or Orichalcum, the priority is the same: get the Tier 2 Anvil as soon as possible after smashing your 2nd Altar.
