I'm not saying that they don't. Just that it was their power level before they became devils that caused them to consume more than one piece.

You're saying that more than one of the same piece used on someone gives a person more of a boost than one piece does. But consuming more than one piece means you have high power/potential.

It's a simple matter of Mathers' worth being 100 and a regular bishop's worth being 20. It you double 100, you get 200. If you double 20, you get forty. Both of them were increased by the same amount, but one is greater than the other because of their high power/potential.

So I would say that consuming two bishop pieces gives you the same boost in magical abilities as someone who consumed one. It's just a simple difference of doubling 20 and doubling 100. It's all about their original worth. And that determines how many pieces they consume.
