Avoiding spoilers, there are really only two items that are *very* nice for Swamp and one of those for the Mountains perhaps beyond - but there rest of the stuff has zero interest for me to be honest.

I've finally managed to find a hole in the Plains ring, and promptly started running into lots of mist - wondering if the Trader spawn locations can be far enough away to block Mistland upgrades?
