FULL DISCLOSURE: The genesis of the class was based on discussion I had the James Spahn on what sort of class my youngest son Connor likes to play. All the material in this book is James' own original work, I am just rather fond of it.
The Forester is basically and elven Ranger with thief and hunting abilities thrown in. It is a 10 level class. The forester gets a lot of interesting abilities to help it in it's role as a protector of the forests including the abilities to hide in shadows and better fighting abilities when wielding a bow. The coolest though is the ability to get an animal sidekick in the form of an Elven dog.
Since this was built more or less for my son he has been using the class in our Old-School game. It plays like a Ranger with a few extra tricks up his sleeve.
