I really dig the Storm Dragons and Tao Chi, particularly the way Tao Chi stays just barely out of wire-fu territory.  The martial arts powers from Enter the Zombie are a lot more visually impressive, but don't quite fit with the WitchCraft vibe.  And yet, Tao Chi users are sort of limited.  Pretty much, what you can use Tao Chi for is hitting people.  Hitting people is all well and good, but there's more to life than that.  So I've written some new powers.  None of these are playtested yet.  I'd be interested in hearing from anyone who uses them.  Or who just wants to talk about them, for that matter.

Body Equilibrium

Masters of this ability can perform amazing feats of agility, running up walls, nearly flying. To activate this power, the Chi Master must spend enough Essence for the effect he wants and roll Willpower + Body Equilibrium. Two points will allow the character to double his leaping distance, and eleminate any penalties due to treacherous ground. 4 points will allow the character to triple his leaping distance and run up walls at his full running speed. 6 points will allow him to run along any solid surface, even if it would not normally hold his weight (also useful for not tripping landmines), and jump 4 times his normal distance. He is immune to being tripped or otherwise falling, so long as there is something under his feet. 8 points will allow him to nearly fly, jumping 5 times his normal distance, and running even across water. Body Equilibrium lasts for one Turn per Success Level.

Circle of Awareness

The Chi Master has learned to attune his Chi to the world around him, becoming supernaturally aware of his environment. To establish the Circle, the Chi Master spends 2 Essence per yard (meter) of radius, and rolls Perception + Circle of Awareness. The Chi Master cannot be surprised by anything that originates within the bounds of his Circle. He gets to defend against any attack, so long as he has actions available to do so, regardless of direction. Similarly, The success levels The Circle test are added to any Perception tests he makes. The Circle lasts for Success Level in minutes. If the Chi Master wishes to maintain his circle for longer (for instance if he is standing guard), he may maintain the circle for longer by spending 1 more Essence to extend the duration by as many minutes as he originally earned. This power is very meditative in nature. A Chi Master must be completely focused on one task to use it. Activating your Circle of Awareness for guard duty, and then playing video games will produce very high scores on your video games, but will not really help you with guard duty.

Fade from Mind's Eye

This technique allows the Chi Master to subtly redirect the flows of Chi so that those around him are unaware of his presence. Masters of this technique can literally walk into a room full of enemies, strike, and flee without being seen.

To activate this technique, the Chi Master spends 3 points of Essence for each -1 penalty to Perception tasks relating to him. The effect lasts for a number of minutes equal to the Success Levels he generates, and may be extended by paying 3 points of Essence for each additional minute. While so protected, the Chi Master is very difficult to spot, so long as he makes reasonable efforts to disguise his presence. He must remain hidden with some level of cover or concealment for the power to work, but far less than might otherwise be necessary.

Anyone who sees the Chi Master while he tries to activate this power is unaffected, so wise Chi Masters either activate it before encountering witnesses, or use some sort of distraction, like flash bombs or smoke grenades to provide cover.

I may add to this later.  I have ideas for a few more that I've never quite hashed out.  And I'm still thinking about how I might undertake Greater Tao Chi abilities.  My favorite method is to say that Chi Mastery 10+ substitutes for the "Old Soul" prerequisite for Enlightened, and the Greater Tao Chi powers are really just Abhijaha powers with a new name.
