Step-by-step guide

What to do first

Defeat The Elder for the Swamp key, find Sunken Crypts in a Swamp, and mine their Muddy scrap piles with any pickaxe. Take the scrap iron to a Smelter with coal to make iron bars. Under normal portal settings, scrap and bars cannot enter a wood portal, so plan the return trip before filling your inventory.

Prepare the trip before entering a crypt

  1. 1

    Bring the Swamp key from The Elder. It opens crypt entrances and is not consumed by each door.

  2. 2

    Pack a repaired pickaxe, poison resistance, current food and a way to refresh the Rested effect. An antler pickaxe can mine the scrap piles; an iron pickaxe is not required to get your first iron.

  3. 3

    Scout for crypts before committing your cargo route. A small patch of Swamp may have no useful crypts.

  4. 4

    Leave a recovery portal in a safer position and arrange a boat, cart route or local smelting setup for the metal.

Work through the crypt in sections

Muddy scrap piles block passages between rooms. Mine a manageable opening and check the next room before removing the whole barrier. Draugr, blobs and enemy spawners can turn an unplanned opening into a fight in a narrow corridor.

Check crypt chests as well as piles. Pick up Withered bones for Bonemass and read any Vegvisir you find while you are there. Mark explored crypts so a later trip does not repeat the same search.

Not every mined section drops iron. An empty swing or a pile that yields other materials does not mean you used the wrong pickaxe. Deposits do not refill after you clear them.

Bring scrap home and smelt it

StageWhat to doCommon mistake
Inside the cryptKeep collected scrap somewhere you can retrieve safely between loads.Mining more than you can carry without a plan to return.
Leaving the SwampUse your planned cargo route; a wood portal is for you and allowed supplies, not restricted metal.Assuming smelting first makes the metal teleportable.
At the baseFeed scrap iron and coal into a Smelter and collect iron bars.Looking for iron bars in the Forge before smelting.
Spending the first batchChoose the next bottleneck: a Bonemass weapon, a tool or a construction unlock.Using the entire shipment on upgrades you do not need yet.

If you cannot find enough iron

Search another substantial Swamp rather than repeatedly clearing the same area. Crypt distribution varies by world. Buried outdoor scrap and Oozer drops can supplement a run, but they are not a guaranteed replacement for crypts.

Later, Ancient swords and armor in the Mistlands provide another salvage route. Keep that option separate from a new player's Swamp plan: reaching the later biome safely is a different requirement.
