Q: Fifthly, am I correct in thinking that the "before the challenge" clause negates any Chi bonusses or penalties inherent in the challenge, such as those created by Asahina's Breath and the Dragon's Heart? If so, is the Double Chi trait still lost for a challenge using the Dragon's Heart?
A: Yes and yes. Jeff Alexander, "replies to 1-2 July", 5 Jul 2001

A: Yes. When you play Dragon's Heart, your personality loses the Double Chi trait until the end of the turn. Playing Judgment of Toshiken doesn't give Double Chi back to him, it just lets it work as normal. By the time you can play JoT, your personality doesn't actually *have* Double Chi, so it can't work in any way for him. That is a nifty way to get around the Chi penalty from Dragon's Heart, though.
