Note that chests are often trapped, and that the skill Remove Trap can only be learned after gaining 50 points in this skill and in Detecting Hidden, in order to learn disarming traps. Another way to avoid traps is to cast telekinesis to open the chest from a safe distance.
Training of course involves usage of the skill. After first training with a thief up to 30 skill points, practical use is needed; meaning lock picking.
