How to find Katah Chuki shrine
The most difficult part of Katah Chuki shrine is getting to it. It’s northeast of Central Tower, near Hyrule Castle. But to get there, you’ll need to fight (or avoid) several Guardians.
Katah Chuki shrine fight and rewards
Inside, you’ll find a minor test of strength, which involves a Guardian Scout II. As always, use Guardian weapons, because they’re the most powerful against their namesakes. And use the pillars as cover when the attacks get too strong.
Your enemy wields a Guardian Spear, which you’ll get as a reward for defeating it. You'll also find a treasure chest with a Royal Halberd on your way out, just before meeting Katah Chuki and collecting your spirit orb.
