Tin Deposits are resource nodes in Valheim where you can obtain tin ores. When smelted into tin, it is useful to combine with copper to create bronze which is the base of strong weapons in the game.
Here is where you can find Tin Deposits in Valheim, and how to gather them.
Valheim Tin Deposits: Where to Find Them
Tin Deposits can be found in the black forest biomes of the map. They are relatively easy to spot and appear as medium-sized rocks with distinct dark and silver-colored intrusions peaking out of the ground.
To mine them, you will need a pickaxe, and once mined they do not respawn. Additionally, they cannot be teleported to another area. They do break easily after one chunk of it is mined.
Once you get the ores, you can smelt them in a smelter, using coal as a fuel. You can use the smelted tin for its own tools, or go to a forge and combine it with copper to make bronze.
