The resolution of disputes through dueling is a central part of Rokugani culture, and duels are an important game concept in L5R, dating all the way back to Imperial Edition of the CCG. In a duel a single character is pitted against a single opposing character, all as part of a single action. This stands in contrast to a conflict, which will usually involve multiple characters over multiple actions.
There are military () duels, political () duels,  and glory () duels.
A duel is initiated by certain card effects between two characters.
- Players use their honor dials to secretly bid a number from one to five.
- Players simultaneously reveal their selection.
- The player with the higher bid pays an amount of honor equal to the difference to the lower bidding player.
- Each player adds the bid to the skill of the character. The player with the higher result wins the duel.
