Skip Rin Oyaa Shrine Puzzle
To skip the puzzle, take the orb and stand in the middle of where the orb is supposed to go. Put the orb down and use the Stasis Rune to freeze it. Then, run up to the platform that rises up and wait for the rune to wear off. The orb will roll into it's place, raising the platform and thus, skipping the puzzle entirely.
