Need some help/to play with

I’ve been playing this game roughly a month(still learning) and was wondering if anyone would like to help me grind or play in general? Still kinda new to this game and don’t know the ins and outs or what build is good etc but each day I am learning and getting better. I have finished the story mode so it’s just grinding for materials getting my characters to their strongest getting weapons and having fun tbh I play on PlayStation but open for all(p.s if ur here for a long term to help even better :)
