How to Get Necro Armor in Terraria — Step by Step
Defeat Skeletron for Dungeon access
Necro Armor requires Bones from the Dungeon in large quantities. Defeat Skeletron at the Dungeon entrance at night to allow safe exploration. Without defeating him, Dungeon Guardians insta-kill players below the surface entrance threshold.
💀 Defeat Skeletron first — Dungeon Guardians block entry; fight him at Dungeon entrance at nightFarm Bones from Dungeon Skeletons
Descend into the Dungeon and kill Skeletons, Skeleton Archers, Angry Bones, and Armored Skeletons — all drop Bones at high rates. For a full Necro Armor set you need approximately 120 Bones. Use a Water Candle + Battle Potion to maximize spawn rates. This quantity is achievable in 5-10 minutes of active Dungeon combat.
🦴 ~120 Bones needed — Water Candle + Battle Potion in Dungeon = 5-10 minute farmCollect Cobwebs from underground caves
Cobwebs are the white web materials found throughout underground cave systems — they appear as white clusters on walls and ceilings in most underground areas. Hit them with any weapon or tool to collect them. You need approximately 30 Cobwebs for the full Necro Armor set — easily farmed from any nearby underground cave in 5 minutes.
🕷️ Cobwebs on cave walls — hit with any weapon to collect; need ~30 for full setCount materials and head to the Iron Anvil
For full Necro Armor: Necro Helmet (~25 Bones + 10 Cobwebs), Necro Breastplate (~50 Bones + 15 Cobwebs), Necro Greaves (~45 Bones + 10 Cobwebs). Total approximately 120 Bones + 35 Cobwebs. Check exact in-game amounts at your anvil — these are approximate values. Collect a 20-30% buffer beyond the minimum before crafting.
📊 ~120 Bones + ~35 Cobwebs total — collect 140+ Bones for a comfortable bufferCraft all three pieces at an Iron or Lead Anvil
With both materials in inventory, craft at the Iron or Lead Anvil. The Necro Armor pieces are found in the armor section of the crafting menu. Craft all three pieces and equip the full set to activate the 20% ammo reduction set bonus.
🔨 Craft Helmet + Breastplate + Greaves at Iron Anvil — equip all 3 for set bonusUse the ammo reduction with your best ranged weapon
The 20% ammo reduction means every 5th projectile is free — over a boss fight this saves 50-100+ bullets or arrows. Pair Necro Armor with the Minishark (Arms Dealer) or Star Cannon (Fallen Stars ammo) for maximum pre-HM ranged DPS. The ammo savings become extremely valuable during long fights.
💰 20% ammo saving = 1 in 5 shots free — pairs excellently with Minishark or Star CannonPro Tips
Necro Armor is specifically the best pre-HM armor for RANGED builds. Magic users prefer Jungle or Meteor Armor; melee players want Molten Armor. Choose based on your playstyle.
Cobwebs also drop from Cobweb-throwing enemies (Web Slinger in Underground Jungle) and appear abundantly in the Dungeon itself. Farm Bones and Cobwebs simultaneously in the Dungeon for efficiency.
The 20% ammo reduction stacks multiplicatively with other ammo-saving effects. In Hardmode, Necro Armor is eventually replaced by Hallowed Headgear set or Shroomite Armor, both of which also have ammo bonuses.
For the Wall of Flesh fight specifically, Necro Armor + Minishark or Star Cannon is one of the strongest strategies. The ammo savings keep your damage output sustainable across the full Underworld run.
Skeleton Archers (also in the Dungeon) drop the Marrow weapon — a bone bow that auto-shoots Bone Arrows. Worth looting during your Necro Armor farming session.
Necro Armor is the clear choice for ranged-focused pre-HM players. The 20% ammo reduction set bonus pays for itself across every major boss fight and is particularly valuable in the resource-limited pre-HM game stage. The farming is quick — 10-15 minutes between the Dungeon and nearby caves provides all required materials.
