Easy to understand psyker melee build?

I've been diving back into the game lately, and the sniper Pyro psyker i created feels really underwhelming compared to alot of the companions. I'm big into owlcats games, but the system feels odd to me. Can anyone help me, barney style, make what I want?

I want to be a force sword wielding(seeing as they just added 12 and they are cool asf) pysker. I want to be able to just dive in and chop up enemy's. Maybe occasionally drop a cool ranged psyker damage nuke. Dogmatic/iconoclast mix.
