Etrian Odyssey » Class Skill Trees
I've been playing Etrian Odyssey and was looking around for skill trees so I could plan a proper party. Nowhere I looked offered what I was looking for, so I gathered the data and made my own diagrams! After a little sprucing up, it turned into a FAQ.
Etrian Odyssey » Class Skill Trees, ver. 1.1 — updated 2012-08-06
It features fairly easy-to-read diagrams and skill cost highlights so you can plan your skill spreads accordingly. Enjoy.
