I don't recall using any outside aid when I was hunting them down... you'll be able to see a lot of them from high vantage points, shrine quests are typically given in obvious places, and the Sheikah Sensor should point you towards any remaining ones while exploring normally.Thank you for the feedback about the dragons. I definitely have some work left to do.
NO SPOILERS PLEASE but, is it possible to find all 120 shrines without help? Has anyone done it? I have 112 now, but no ideas as to where the remaining ones are, no clues, no sidequests, and no area on the map that I haven't seemingly already explored. Just curious how much more time I should dedicate to traversing across places I've already gone when my sensor remains totally quiet.
