Saves a lot of time ducking out and back in most dungeons if the quest chest isn't immediately present.
Also seems almost 80% or so to go to quarry from Hillsfar via the first ? path (three inputs). I haven't always ended up at the quarry, but it did most of the time when I was testing it. Seems linked to frames you enter the overworld map on because it was 100% using the same save state on the overworld.
Return from Quarry to Hillsfar seems about 50/50 but I haven't tested it as much just mashing A after leaving the quarry map.
Definitely time to save still with better map RNG and fewer avoidable falls on the horse sections.
