All feedback is welcome. I want to make sure I’m not wasting any stats or anything. There were some skills I wasn’t sure if they would scale well or not. So all info is helpful 
I think this build is no good. I am petty sure that you don’t know what you did.
Cleric is fine.
Priest c1 without Bless will have a very hard time grinding alone. I think you want to skip Bless Because it has no scale. If you want, you can do this in this hard way.
But at the Priest c2, you should get a least lv.2 Revive and decrease Monstrance to lv.8 should be fine. Also this Priest c2 is gonna be the most difficult character to grind in the game. You have to press Z for 20hours or more. This is fine if you can do or have some friends for some helps.
This thing went wrong at Sadhu. There is only Safety Zone lv.5 to protect you for 10 hits per min when you do Out of Body or Possession all the way to end of the game. You will rage from every interrupts. Or maybe you have friends to protect you all the time? And what is this build good for? It have a lot of buffs from Priest, like support build. Then it has some unreliable damage skills from Sadhu. This Priest and This Sadhu have no synergy too.
This build can be done. But what for?
