While in the Rivertown map, go to Dwarven Village and Dwarven Hills. Find a cave with an entrance that is blocked by rocks. Keep moving them from cave's entrance until you can enter. You will find a sword called "Blade Of Chaos". This sword is very powerful, but its features and abilities are random. Each time you start a new game, this sword changes. If the sword has the "Frost" ability, keep it. When you hit enemies they will enter a freeze state. They cannot hit you and this is useful when facing strong enemies.
