These skills are gained by those who choose the profession of the Thief. Since the Thieves have only one guild (The Thieves Guild), they are only associated with that guild. They tend towards areas of physical discipline, litheness, and robbery. The Thieves gain the basic ability of Thievery, the subterfugial art of Stealth, the skill of laying traps, the art of picking locks, the lore of poisons, and the combat skill of archery. See Section 7.11.2 on Trapping, Section 7.11.3 on Poisons and Section 7.11.1 on Archery.
Thievery is the basic and most potent ability of the thieves. It is shared with no other guild. It is your ability at pick-pocketing, picking locks, archery, slight of hand, and robbery. It will enable the thief to steal items from other players without them noticing. Thievery allows the thief to disarm their enemies of their weapons and pilfer their gold. It should be noted that, when used, Thievery can make its user a most unpopular person. However, when developed to its higher levels, it makes the thief both feared and valuable.
Stealth is the skill of subterfuge. It is your ability to conceal yourself from others, to act with slight of hand and speed of foot. You can hide yourself, hide items, travel around undetected, ambush the unwary, and track your prey before attacking them. Those practised in the art of Stealth will find themselves able to call upon the element of surprise in combat, and to escape the scene of a battle quietly and without danger. The skill of Stealth is shared with the profession of the Rangers and to a lesser extent, the Sorcerers.
