As long as you remain cautious, you can often find valuable treasure or Important NPCs.
You can and should be exploring everywhere you go.There are plenty of weapons to choose from - and most all of them are effective enough to use throughout the game, just remember to upgrade the ones you enjoy using the most so they become more powerful.Each time you return to an area, you'll get a bit better as you learn more. Don't get frustrated: learn how encounters work, what types of attacks bosses use, and where traps are. You're going to die - there's no way around it, and even the best players eventually mess up.Don't hoard Souls - it's the currency you need to level up, and you'll usually want to spend them soon instead of running the risk of dying in place where they are harder to retrieve.While your starting class can give an outline of the character you want to be, you'll soon be able to grow in any direction you wish, so don't worry if you don't want to be stuck as a Warrior, etc.
