Gisei Gisei no Mi

Somebody told me there is no more devil fruits to be made. I want to prove them wrong

Introduction
The  Gisei gisei no mi or sacrafice sacrafice fruit is a devil fruit that allows to user to sacrafice something that belongs to them to gain physical might. A example of this would be the user sacraficing his ear in order to gain the strenghty to cleave through a mountain.

The boost one gets is equal to the value they place on there sacrafice. So a guy who loves to listen to music giving up his ears gains more power than a blind man giving up his eyes.

Weaknesses
The user suffers from standard Devil Fruit weaknesses.
