Praying to Cruentus will have various results.
If he is pleased, he will either recommend you to his master, [[Mortifer]], or give you a bottle of [[Troll blood]]or enchant your weapon. Unlike most gods, he will not summon a new limb if you are missing one, since drinking troll blood will have this healing effect by itself.
He may also summon an [[angel]] or his archangel Gladius to assist you.
