Body Double

Body Double (分身体) is an Extra Skill acquired by Ifrit, Rimuru and Souei.

Abilities
It allows the user to make one or more copies of themself depending on their proficiency and magicules used.

Ifrit's Version
Ifrit can create a large amount of Body Doubles in the double digits, but they're all fragile copies that are easily destroyed.

Souei's Version
Souei can create up to five Body Doubles at the same time which can be fully controlled by him regardless of distance. In physical ability they're all the same, but in terms of energy they're inferior in comparison. He can use his Unique Skill through them if his main body is close enough, but there's a small time lag that can prove fatal if the opponent exploits it.

Rimuru's Version
Rimuru can create one copy which he can only control completely within a certain distance, however, the Body Double can have its appearance further modified and has no real limit to its power as depending on how many magicules Rimuru endows it with, its power can be very close to the original body. If its close enough, Rimuru can use Unique Skills through it, albeit with a small time lag.
