When you are in Rivertown map, Go to Dwarven Village & Dwarven Hills. You must find a cave that its enterance was blocked by rocks. Keep moving them from cave's enterance until you can access there. You'll find a sword called "Blade of Chaos". This Sword is very powerful. But its features & abilities are random & each time you start a new game, This sword changes. If the sword have "Frost" ability then you are in luck, Because when you hit enemies they go into freeze state so they can'y hit you & this will help you a lot when you face with strong enemies.
