Need advice for build

I just got the Grimoire yesterday and have it equipped with my Nekros Prime. I am slowly working towards getting mods for it, but I was wondering if there are any specific mods that might pair well with Nekros? I couldn’t find much on Overframe and figured I would ask about the mods here. What do you all like to us for your Grimoires? Doesn’t have to be on theme with a summoner build or not 😁
