Favor of the Kami is an exploration trophy for honoring all 16 Shinto Shrines on Tsushima. Each shrine is a climbing route that ends with a major charm.
Look for the torii gates that mark each shrine's path. Climb to the top and press R2 to honor the shrine. Do all 16 across the three regions.
Get the grappling hook from The Iron Hook first. Several shrines also have hidden altars along the climb.
