Swim

Swim is a skill that allows you to do just that. It is based on Endurance, your ability to... well, endure the rigors of swimming. The higher your skill level the better your chances are of crossing a body of water without sinking and dying. You also swim faster the higher the skill is. Your swimming is also effected by the weight of the items in your inventory, the more weight you carry the more likely you are to sink/swim slow. You can learn Swim from Smokey in Escheton Outfitters, or EO on the map.
