Change "I Do Not Know Him!" to just, "Denial of Christ".
No, other title is better.
I feel like it would be more fitting to convert them for 3 turns and give them the ability to protect 1 NT lost soul, as well as making it territory class.
That might be overpowered since he can then band to creeper and protect 4 souls every turn.
I don't like Prayer and Fasting, unnecessary */6 requirement plus demons are already weak to preblock shenanigans.
