Piaffe at Gerudo Canyon Stable would like to paint a picture of the giant sword on top of the Gerudo Highlands.
Quest Location
Check on the empty frames on the wall in Gerudo Canyon Stable to start this quest.
How to Complete the Quest
Use Gerudo Highlands Skyview Tower to go north to the Gerudo Summit. There is a Frost Gleeok in the southern part of the summit, and the Forgotten Sword is next to the Frost Gleeok. You don't have to fight the Gleeok in order to get a picture. Just stand some place far away and zoom in on the sword. After you take a picture that has a red exclamation mark symbol on it in your album, go back to Gerudo Canyon Stable and check on the empty frame again to complete the quest.
Quest Reward
Piaffe gives you a Pony Point, and a Chilly Mushroom Risotto. If this is the last painting to go up, you also get a Diamond and five Enduring Carrot Cakes.
