Ideas for Church Grim attacks.

You may have seen the rough sketch of the creature i'm going to design called a Church Grim, in which i posted some lore about the creature, giving it some attacks and whatnot. I don't think i'm satisfied with it just being a necromancer and being a ranged fighter. So... I ask you, indispensable and mighty peons of reddit to help me think of some attacks for the beast. Pretty please? Think of something out of the box. I'd love to hear your ideas!
