Skystrider Glider and interact to
Sundancer.
While riding it rapidly press
Soothe extra button. You keep getting damaged while riding the rare, so dont waste your time.
When
Sundancer will calm down, it carries you to the spot where you have obtained the

Now you can talk to rare and accept its challenge. The fight starts, rare is tough. Bring its hp down to 10% to pass the challenge.
