Only grind for Eiter would be finding the extraction items and then setting them up - that and those who think that the magical roots don't replenish the resource when it's "dry" so they move their extractors constantly lol.

I've only got like 3 a short walk from my plains base and I didn't find them to be a grind. Getting the feather cape however is more grindy which was annoying because of how jagged Mistland terrain can be.
