Koumu Koumu no Mi

Introduction
The Komou Komou no Mi is a paramecia devil fruit which turns it's eater into a "perfect Engineer". This allows them to quickly and easily assemble any mechanism they can imagine, given it's raw materials

Usage
This fruit is the twin of the Mecha Mecha no Mi, but also it's opposite. While the Mecha Mecha no Mi could spontaeneously generate a device from it's blueprint, this fruit instead turns the user into a walking assembly line, giving them accesss to essential tools (in much the same way the Ope Ope no Mi gave it's user surgery implements), and allowing them to easily generate a blueprint for a device, then slowly construct it out of necessary raw materials.

Weaknesses
The user suffers from standard Devil Fruit weaknesses. Also, it cannot be used to create a device when there are no usable materials in the area.
