I know how to train all of the rest of them, fishing, research, etc., but I can't get them to train in devotion. So I've been using youth on the ones that have it already, and hoping when they start making babies that their babies will inherit some of their devotion skill. This is driving me nuts. In the strategy guide all I found was that villagers gain devotion skill from trying to convert blue masks. There are no blue masks, yellow or red masks left! Anybody know what to do?
