Low skills represent deplorable crafts and practices that no honorable soul would even imagine taking up. Practicing any of these Skills will usually result in a loss of Honor for a samurai who does so, and if done in public, quite possibly Glory as well.
Although generally a dishonorable practice, stealth has its uses in such situations as hunting or while scouting during a military engagement. For most samurai, however, these are necessary evils, and under any other circumstances, no honorable souls will ever dare disgrace themselves by sneaking about in the shadows like common criminals, or failing to face their opponents like true samurai would.
The dexterous manipulation of small objects for the purpose of misdirection or concealment is not looked upon favorably by most honorable samurai. The code of Bushido flatly calls for sincerity in action, word, and thought, and such parlor tricks smack of deception and dishonesty, which no honorable samurai can abide.
The manipulation of others through the use of threats, both stated and implied, is an oft-employed tool for those who have left their honor behind. Even bushi who are generally honorable but have a strong sense of pragmatism will occasionally abandon decorum and threaten those who refuse to cooperate. It is a shameful act, but one that many are willing to commit (and promptly forget) in order to ensure the successful completion of their duty.
Documentation is very important in Rokugan, from information on an individual's illustrious lineage to travel papers issued by magistrates, and even the official Imperial Decrees of the Emperor himself. Those with an eye for detail, a steady hand, and a distinct lack of honor can take advantage of this system by falsifying such papers, either for their own use or to sell to others.
When a forgery is created, the result of your Forgery / Agility Skill Roll should be noted. This is the TN for others to detect the forgery using an Investigation / Perception Skill Roll.
