Sometimes you need help. You are badly wounded, don't have enough cotton, so you put some botonised stuff in an altar and pray. You god, bandages a medium+ wound. You are starving, already fasting, so you put your clay pot in the altar and pray, you get a basic casserole that gives you 50% nutri. Dying of thirst, you put your waterskin or clay jar in and pray. Each of these only works once per day and hits your faith.
