If he makes magic food once per day, that should be enough to sustain him. Here is a link to a
great story by someone in a similar situation. Hang in there!

Good luck!

He died . I Have a new tribe now

Magic food isn't enough to sustain a single villager, if I recall, though it does help. Who needs a chief for a single villager, anyway? He has no use without other villagers. He can't direct work, he can't teach, he can't point out collectibles that anybody can collect. All he can do is make not enough food to live on (Unless you pause alot) and eat.

I'm sorry!
A new tribe is always nice and I wish you good luck with it!
