I mean, there’s literally one mistlands exclusive item that isn’t teleportable, and it’s the extractor piece that really never has to leave the mistlands in the first place. This is like the only thing in the entire progression tree of mistlands that probably requires sailing material around (unless you’re lucky with biome arrangement).

It’s inconvenient, sure, but once you do it you never have to do it again, which is far better than having to scavenge and sail iron back to your main base each time you run out of it.
