How to find Chaas Qeta shrine
Chaas Qeta shrine (A major test of strength) is located on an island in the ocean in southwestern Hyrule. You can see it from the beach in the Hateno Tower region, down the cliffs behind Hateno Ancient Tech Lab. It sits on Tenoko Island in the Necluda Sea. (See the gallery above for a visual representation of its location.)
How to defeat the Guardian Scout IV
The Guardian Scout IV in Chaas Queta shrine is among the most difficult enemies in Breath of the Wild, so it pays to have many hearts, upgraded armor and food and elixirs to help you. Guardian weapons and the Master Sword are your best bets — as are ice arrows, which freeze the Guardian and give you a few seconds to regroup and attack. Check out the video above to see how we took it down.
