"Crom, I have never prayed to you before. I have no tongue for it."
In our uncaring, hyperborean waste, divine healing doesn’t exist. However, characters can cry out for a blessing prior to a battle, offering up sacrifices in the hopes of currying a god’s favor. With a successful spellcheck the character is granted bonus hit dice to distribute to amongst allies as they choose.
Actual bonus hit points are not determined until battle is joined. The hit points are temporary and any remaining points are lost at the end of the battle.
Any character can beseech a god, rolling a 1d10 + Personality modifier. War bands can improve their odds by offering up sacrifices, which can be in blood, treasure, or both.
