Spawn Displacement is a glitch that allows you to spawn anywhere inside of a shrine.
By using the overworld or any shrine, we can enter a shrine, but have our spawn displaced. This glitch is extremely easy to execute.
Simply save inside of a shrine, then go to any climbable edge in the game (Cryonis blocks work) and move close to the edge until the prompt to climb down appears. Now press A and pause at the same time, then load your save file.
Mash the X button to skip the entry cutscene. You should now have spawned in an unintended location.
