Metal

A category of resource used to create weapons, armour, and furniture, different kinds of metals can be smelted from various Ores and Scraps.
Unlike most items the player can carry, Metals in both their processed and unprocessed forms cannot be transported through portals. The player must resort to carrying these resources by Hand, Cart, or Ship.
=== Transportation Methods ===
Many of these methods can be combined. Using a Cart as well as world hopping can make the process of gathering metals significantly less labour intensive.
==== Ship ====
A Ship can be used to extend the player's inventory, and allow for longer resource gathering trips.
==== Cart ====
Acting as an extended inventory, the Cart can allow you to make longer trips before having to deposit your resources back at your base.
==== Player Inventory ====
Simply requires having as much as you can carry in the player's inventory and then running between locations. The stamina boosting reward from defeating Eikthyr can help speed this up.
==== World Hopping ====
Whilst metals do not travel with the player through teleports, they will travel with the player between worlds. As a result of this it is possible to quickly transport large amounts of these heavy resources without the need to spend hours traversing the world.
This methods requires 2 worlds. and is most effective when one world has a portal between the two places you wish to transport metals between. The second world will require a chest for you to use as an intermediate holding place.
# Begin by gathering as much metal as you required
# Log out of the world you are mining on, and log into your second (holding) world
# Deposit all resources you wish to transport
# log out of the holding world and log back into your primary world
# Travel (by portal) to the location you wish to have the ores
# Log back into the holding world and collect all the ores
# Log back into the primary world at your desired location.
#If you mention this method in the Valheim discord, people will get really mad.
