Take 30 or 50 faith, nothing in between. Use good miracles, an Occult weapon with a Divine as backup. Also if you are going for Grant you will need a lot of Strength so until you get all the way up there take a strength scaling weapon as a backup backup to your other weapons.
Leroy's set works nice for RP purposes if you want a heavy faith build. Likewise Sanctus is a nice shield that heals health and works nicely in tandam with two-handing Grant.
Vitality: Personal Preference
Attunement: 19 or 23 if you are wanting to make full use of Miracles but sprinkle them as you go, don't spend consecutive levels in it
