How to find Hia Miu shrine: Hia Miu is located in northwestern Hyrule, in the Hebra Tower region. It is essentially in the very far northwestern corner of the map, so you shouldn't have difficulty locating it if you venture to that area. (Browse the gallery below for the precise location.)
How to defeat the Guardian Scout IV
Wear the strongest armor to this battle that you can, and bring guardian weapons with high damage output. Begin by drinking an elixir that improves your attack power, then move in close and strike your opponent with Flurry Rush attacks when possible. After it attacks a few times with both weapons, the guardian will typically use a whirling attack, so get out of the way and then move in quickly to land a few more strikes. Elemental arrows also work nicely when you need to attack from a distance. When the guardian collapses and a laser tracks your movement, the guardian is almost dead and you have a limited amount of time to hack it to pieces before it explodes (possibly taking you with it).
We’ve also included a video above that shows another major test of strength. It’s from a different shrine, but the same principles apply.
Your prize when you win is a Sapphire and a spirit orb, as well as the usual assortment of guardian parts.
