A player, 7 May 2006
Somehow, I get to increase Ohan's Chi by 1 (either by attachments etc). My opponent uses Impromptu Duel on one of my Personalities, and I refused. Can I gain his Honor instead by using Ohan's ability, since the honor gain is not a esult of the duel?
relevant texts:
Shosuro Ohan
Political Reaction: Before another player gains Honor, bow Ohan: You gain the Honor instead. Use this only if the gain is less than Ohans Chi and is not a result of a battle or duel, and the player is above his Starting Family Honor.
Impromptu Duel:
Limited: Target a Samurai Personality you control: Target a Personality controlled by another player. Your Samurai challenges the other Personality. If he refuses, Dishonor him and gain 4 Honor. The winner gains 2 Honor.

No. Rules Archive, Duels, Resolution: "'Honor from a duel' refers to honor gains that are written as part of the action (or non-action card effect) that initiated the duel." The gain from refusal is part of the action, so is from a duel.
