Stealth is the skill of subterfuge. It deals with your ability to conceal yourself from others. Hiding is directly compared with perception to discover whether your concealment is sufficient. In addition to being able to hide yourself, you will also be able to hide items and depending on the location and your skill and of course, the size of the item being hidden, you will be able to hide a great deal out of harms (or in harms) way. You may also TRACK others as they make their way around allowing you to slink about unseen and reap the benefits of their knowledge.
