I am currently working on a little expansion for Otaidokan with new skills and equipment. 

The following skills can be chosen only as initial skills for characters with bushi background:

One Cut: Ignore your opponent's armour. 

The Way of the Water: You can fight blind and/or waist-deep in water without penalty. 

Rider of the Wind: You have Advantage when horseback fighting and can do all sorts of tricks with your mount.
