Okay, this is getting kinda ridiculous with the powers here. How is a Greater God fighting against a "Surpassed" Superior God and hurting him with the ability from like an SS-class Hunter/Item. Even if the ability is enhanced by his divine power(which as far as we know, it isn't) it should still not do that to a God like that.
And I'm only annoyed cause it seemed lazy, that pen could've been an interesting tool that's used to literally write out parts of the fight by using his causality or force him to do bad moves or take more damage by changing the "script". It would've been more broken sure, but would at least make more sense.
