Want to hunt for swamp creatures on the Island but don’t want to deal with these guys? The “Gulch of Lamentation”— the easternmost swamp region by the coast— has no Rhynio spawns! This also applies to the swamp area around the green obelisk, along with the thin strip of swamp river immediately north. Generally speaking, you’ll be safely Rhynio-free if you stay east of that obelisk.
