Question Sataniel. (Persona 5)

Recently scriptel of Nataniela and with him went wet twins. It was difficult, but could. Then went to test it on the reapers and a little prifigel from damage which he does 200 damage with severe skill when bapah attack.....I certainly like that he resist all, plus the twins drove the thing which block all but Amid damage, but...you Can do something to increase his damage? May need to craft special, just if you compare it to the example of the Messiah Picasso DLS(person) with list Megidolaon inflicts 1000 damage when bapah when Sataniel a maximum of 500.
