Does Chi help Theatrics?

[Dainoji]

BUt my question is really, does having high chi help passive attacks?

If the passive skill has chi listed as one of its core attributes, then yes chi will help. As an aside, I can't think of anything negative to having a high chi except other attributes being lower than you might want.

Correct.
And that's exactly my beef with it: The high Chi itself doesn't hurt my Theatric; It sure as hell doesn't help either, yet it "consumes" space , better used for other stat-points.(Hard time getting some extra Stam and Pres on Marly Diettrich...)
