The Incomplete Stable is a side quest in Zelda: Tears of the Kingdom that takes place inside Lookout Landing. Here, you will help an NPC named Karson mend the stable’s roof. Completing this side quest will unlock the mini stable in the region where you can board and register your horses and retrieve them whenever you want.
Talk to Karson in Lookout Landing
To start the Incomplete Stable side quest, go to the Lookout Landing north of Hyrule Field.
After getting there, you need to find and talk to the Karson. Near the main gate, he will be located on the south side of the Lookout Landing (-0245, 0060, 0019).
The Incomplete Stable side quest will begin once you have successfully started the conversation with the Karson. If you are having trouble talking to the NPC Karson, you might not have completed the Regional Phenomena questline of the Hebra region.
Fix the Roof of the Stable
All you have to do here is help Karson fix his stable roof. It is an easy objective that will complete The Incomplete Stable in Zelda: Tears of the Kingdom.
First, you need to get your hands on the small plank which is located on the right-hand side of the stable. Now, you need to pick the plank using the Ultrahand Ability.
After picking up the plank, you need to find a way to the top of the roof. For that, travel to the back of the stable where haystacks are placed. Use these haystacks as stairs to jump over to the roof.
Once you are on top of the stable roof, you will easily locate the gap where the plank needs to go. As the plank is not perfectly square, therefore rotate it to fit the gap perfectly.
Once the planks are in line with the gap of the stable roof, place them down, where they will become part of the roof. Doing so will complete the Incomplete Stable side quest.
Quest Reward
After finishing the repair, you will unlock the mini stable in Lookout Landing by talking to Lester and Karson.
