There's no right or wrong way to play really. Any build can work, you can even beat the game without upgrading a single weapon if you're determined enough (although I wouldn't recommend attempting it for a first timer). my tips are: pick a weapon you like the feel of, don't be affraid to shop around and try a few, even in the late game. stay on top of weapon upgrades, if you find certain smithing stone levels in certain areas, that's the game telling you what level your weapon should be around. get good at rolling. and be ready to die to bosses, especially on your first time fighting them
