Remember, although strength and dex can help with power, the best way to have damage is to upgrade your weapon. Do it with a weapon that you feel comfortable with, and think you can use for the majority of the game. (Drake sword is good till sens fortress. After that it's horrible.) Also, I beat the game with the Pyromancers robes. I find that upgraded it does a lot of protection, while allowing quick movement. Thanks, hope I helped.
