I used Scrying on a Scrying Focus and only saw creatures in the same exact area as me.
This seems wrong, but I'm not 100% sure. Is it supposed to cover more ground? I expected to at least be able to see the entire Ring I was in, not just "XXXX - Interiors"
Do I need SF and GSF to see further?
It should work on the ring itself.
The area you're in may be tagged incorrectly, or it may be an area that is recycled for different sections and thus considered outside of any region. If you're worried about spoilers you can PM me on discord to ask.
