jumping from that position gives link enough hight so that he will roll after landing. shortly before landing press Deku stick and mash A(if you hear the equip sound, but link is still holding the bow in his hand, you did it correctly). now light your deku stick, roll once and get into position, wait a little bit (so that the stick gets long enough) and slash to hit the owl.
we need to do something so that link doesnt try to shoot an arrow. if he shoots an arrow without having arrows, the game crashes. a roll after lighting the stick is enough for that.
elemetal arrows and hookshot also works instead of bow.
it can be tricky because the bomber kid moves around.
dont stand too close to the loading zone. otherwise you touch the loading zone after slashing without the owl finishing its animation
someone on the rando discord asked how to activate the hidden owl for index warp. i couldnt find a video without using shield or doing a long jump.
