Yep you need 10 lynel bows and a long electric sword and and you go to the shrine near the great fairy in gerudo desert and as you get there you should see a camp in the back full of bokoblins and what you need to do is have either a bokoblin mask or majoras mask. Get the hylian shield on and take all their weapons by hitting them once with the electric greatsword. Make Sure they're in a circle.
