Skill levels

[notld]

It's gonna sounds kinda strange, but what I want is to loose my earned attack and speed points. Is there a way of doing that without loosing the rest of the atributes, like life and inventory, and make it so that it doesn't keep going up every passing level?

If that's impossible, here another option: to reset all the atributes. But I do want to keep my combo cards and special atack movements.
Waiting for any answer.
Thanks.

This is probably something that could only be done by some kind of Trainer, or Save file editor.
