Chikairi or Art of Infiltration
By Kuseru

This is the art of infiltration, and includes Toiri no Jutsu the art of infiltrating castles and enemy camps. A character with this skill uses a variety of techniques such as stealth, hiding, climbing, swimming, and even just brazenly strutting to get into a castle or other stronghold of the enemy. For example, to get into a castle may require the character to sneak up through patrols then swim through the moat and climb the castle walls and then into the castle itself all the while hiding from guards and the people who inhabit the castle. The character may also try to just bluff his way past guards and others by pretending that he actually belongs there! This technique actually works, because no one tends to bother someone who looks like they know what they are doing and belong there. Base skill for sneaking into a place is 50%+3% per level of experience. Base skill for attempting to bluff entry is 30%+3% per level of experience.
