A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

If Doji Reju ties in a duel against anyone with the duelist trait (or even another Doji Reju, for that matter), both personalities suffer the effects of winning, correct? I seem to remember that being the ruling involving Reju and Reju duels back in the day.
edit: Nevermind, I found the answer in the comprehensive rules here under step H.
