hard foundation

Exploration Stage: Pagoda of Legends
From: Bao
Description: I have the blessing of the "heavenly archer". I am ready to fight the Wind Dragon. First of all, I need a bow. I used to have a bow. My grandmother gave it to me. But the wind knocked it against a stone and it was cruelly broken. There is no choice...I will have to make a new one. Please find young bamboo from this chedi. It will serve as the foundation for a new "bow of etiquette.
Completed: You brought the young bamboo. Thank you very much! My grandmother turned the bamboo into a sturdy bow foundation, but I have to remember how she did it...
