Sacrificing 1 iron, 1 copper, 1 silver or 1 gold (either in items or in coins) will each generate a different message displaying how pleased your god is with you.
<s>Sacrificing 1 silver will also gain you 10 favor</s> (Does not work. Sacrificing any money will probably not work.), and sacrificing 1 gold will heal all [[wounds]] and fully restore [[favor]]
*Tip: You can get rid of any item that you don't want anymore provided that it fits inside.
