Katosa Aug Shrine is a puzzle shrine found in Akkala, right next to East Akkala Stables, on the pathway to Akkala Ancient Tech Lab.
Katosa Aug Apparatus
This Shrine requires using motion controls to complete a miniature-golf sort of puzzle. You’ll need to angle the large “golf club” and shift your console/controller at just the right force to hit the ball far enough across the platform until it reaches the hole at the other end. If you don’t hit the ball hard enough or it falls off the edge, you’ll have to exit the apparatus controls and then click back onto them so that the ball respawns at the starting point again.
Katosa Aug Treasure Chest
After you’ve gotten the ball in the hole, you’ll be able to finish up this Shrine if you want, but alternatively, you may want to head into the room behind that offers a bonus puzzle for some treasure.
The second miniature-golf puzzle is a bit more complicated as you’ll need to either hit the ball super hard so that it flings over the gap and lands on the other side, or you’ll need to angle your hit and make the ball move along the side path until it rolls down onto the other side. This can be quite tricky to accomplish given motion controls aren’t always the smoothest thing ever, so you might need to do a bit of trial and error to complete this puzzle. Once you’ve done it though, a moving platform between the main floor and the platform with the treasure chest will be activated. When you loot the treasure chest, you’ll get a Great Frostblade.
