Destined to dwell in darkness, shadowed fists move about the battlefield in a black blur, never making a sound as they destroy their foes. Masters of stealth, those killed by a shadowed fist likely never knew they were the target until it was too late.
Combat Training: A shadowed fist may combine combat spheres and talents to create powerful martial techniques. Shadowed fists are considered Expert practitioners and use Charisma as their practitioner modifier.
This ability modifies combat training.
AC Bonus (Ex): A shadowed fist uses their Charisma modifier in place of their Constitution modifier when determining her bonus to armor class with this class feature.
Ki Tension (Ex): A shadowed fist may use two points of tension in place of one point of ki whenever they would be required to spend ki on a ninja trick. In addition, a shadowed fist uses her Charisma in place of her Constitution when determining her maximum tension.
This ability modifies tension.
Expanded Talent (Ex): At 2nd level, a shadowed fist can select a ninja trick in place of a striker art (she cannot select a ninja trick which would modify her sneak attack unless she possesses sneak attack from another class); in addition, she is treated as though she possessed the ninja trick class feature for the purposes of selecting the Extra Ninja Trick feat. All striker arts which would use her Constitution to determine their effects instead use her Charisma. At 11th level and above, she can also select master tricks.
Nimble Shadow (Ex): At 3rd level, a shadowed fist gains a +1 circumstance bonus on Acrobatics and Stealth checks and she treats any Acrobatics skill check made to jump as if she had a running start. At 10th level, she also reduces the DC of Acrobatics skill checks made to jump by 1/2 (although she still cannot move farther than her speed allows).
This ability replaces drill knuckle.
