Ruun Ruun no Mi

Introduction
The Maho Maho no Mi model: runes is a paramecia devil fruit that lets the user create various "Magic" stones with different properties, at the cost of a small quantity of the user's life force.

Weaknesses
The user suffers from standard Devil Fruit weaknesses. Also, the Stones do not generate any energy of their own, and they must draw energy from another source to function. Therefore, they act merely as energy converters.
