In FFA Format, if you invite another player to your showdown and they decline, do you lose focus?

Ruling: No, you do not lose focus if an invited player declines. You only lose the ability to invite that same player again, but you keep focus.

Nuances:

• Focus is never something you "lose" - you can only willingly pass it
• If the invited player accepts, they must play an action/reaction immediately
• You can invite a player to act when you have priority
• If they decline, you retain your priority
