Satorl Marsh is a tremendously huge region- and the Collectapaedia page reflects that, beating even the Ether Mine’s page in sheer amount of stuff. Most notable among these items is the Blue Turnip, notoriously hard to locate. Blue Turnips are found most often at night, in areas where there are waterfalls as well as the waterlogged cave to the West of the final part of the area.
One of the rewards- the Lock On Resist- is not terribly useful, but the rest of the stuff is- especially the equipment, which is all of the quality that you’re going to find at the beginning of the next area- it’s well worth it to make sure you grab every collection item you spot as you wander around.
