ShiKage's Big Bang Paladin Build

Even if you have a Normal sword. Weapon Booster will make it operate as a Fast sword. Speed and Jump are negligible, but as you just said, if Power Strike and Slash Blast connect then the hitbox for Final Attack will activate and damage the monster. As I just proved by you, careful tactics will mean more damage. 2-Hand swords have good range even if they don't add what a shield could, but then again, regardless of what you use, Warriors are up close fighters, not long distance fighters.
