Warriors can specialize in one of two trees: Attack or Defense. Both trees do exactly what it says on the tin. The Attack tree focuses on brute force and unrelenting offense with abilities that allow the Warrior to cleave, smash, and otherwise brutalize anything that stands between him and his goals. On the flip-side, the Defense tree turns the Warrior into a vigilant protector who can put himself in harm's way to protect his allies. If you want more details on the various classes available in Lime Odyssey (and get in on the closed beta), just head on over to the game's official site.
