A few questions about Evil Pieces. First, does everyone's Evil Pieces have the same set values or could someone's strength make a difference. Like if Sirzechs had reincarnated Issei, would he have needed fewer pawns to reincarnate?

Second, does a Mutation automatically require someone alone, or are their cases other pieces need to be used with it? I'm not sure due to some fanfics showing Issei needed multiple, and I wonder if this is a misunderstanding due to half of Issei's pieces mutated in later volumes.

And the last question, what makes the King Piece that enhances someone's power different from the one that marks the owner of a peerage?
