Host tether distance. The slider doesn't actually limit you, you can type in as high value as you want. I have mine at 50
Well, that'll do you fine on the Island, and Rag and Ex for the most part at least, so long as you don't intend to go into any caves alone. If you're talking about the teleporting in certain zones (regardless of distance to the host)? I wholeheartedly agree, please do something about that WC.
