Doublecheck the Avara Documentation. The Docs outline everything you will need to know.
Beyond that, the best place to go for game play hints is the Ambrosia Web Board. Go to http://www.AmbrosiaSW.com/news/webboard/ and then select the Avara discussion board. If you register, and why not, it's free, you can post your question, where it will be read and soon answered by other players and fans. You can also scroll through questions and answers already posted. The boards are also searchable, so if you're interested in something particular, you can look it up!
