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.
Claiming the Throne: Before a player's turn ends this game, if the player, during that turn, destroyed a province in battle resolution, put two or more Rings into play by their own text, and gained 7 or more Honor, he may discard the Imperial Favor and pay 10 Gold. If he does so, he wins the game.
Is discarding the favor for Claming the Throne a cost or not?
ex: Can I use Commanding Favor or Honor or any card that allow me to pay the cost of discarding the favor?

Claiming the Throne does not require that you discard the Imperial Favour "as a cost". You may not instead use an effect that lets pay a cost of discarding the Favour.
