>I was told to get Oberon to make my NP1 Summer Ibuki good

I don't know who the fuck told you that, what summer Ibuki really needs is Castoria or other arts support as filler and you can steamroll 90+% of 'content'. Oberon is just a nice bonus on top of that, but for her he only really has an effect if you have a Black Grail.
