Items Keychain

[trashcanned1 🌳🌳🌳]

Something similar to the Void Bag/Vault but stores only keys (Golden Key, Shadow Key, Temple Key, all the biome keys, keys of Light and Night, and the Keybrand). Rare item dropped by the Armored Skeleton (probably less than 1% because of how common those spawn). This wouldn't really be all that useful to try and get, but getting it naturally just saves that liiitle bit of inventory space.

I don't think it does save any inventory space, though. Especially if you need to keep it in your inventory to use it. When do you ever need to have more than one key in your inventory?

If you are having issues with inventory, then that's a skill issue, not a game issue. You can hold a safe, a void bag, a defender's forge, and a piggy bank all in your inventory, and each of them hold about one chest's worth of items.
