SPIRIT is only good for when you have ultimate maxxed, don't get it before then. You should focus primarily on GUN with mainly some GREENS. The reason for this is his Ira Domini scales multiplicatively off the gun damage, so its good to have a good baseline gun stat before putting money into spirit imo, and the spirit only scales with the blessed damage.
