Oh, lookie! I got Starred.
Warrior is a class that generates a lot of questions and whilst I do not consider myself an authority on the class, I'm happy to answer questions whenever I can.
Here's one before you ask it:
To generate Rage, you must be within 'Attack' range of your target. A lot of your regular skills will have a slightly longer range than this and so to get close enough to generate Rage, you should hit 'Attack' pretty early on in the fight to allow your character to move close enough.
Of course, it's much easier to take more damage when you're closer so make sure you have a decent stock of health potions and herbs.
Running the minigames for Phirius potions is also a good plan.
