Can you win the game during an opponent's turn by conquering a battlefield to reach 8 points when you already control one battlefield and are at 7 points?

Ruling: To score the final point and win, you must score all battlefields in the same turn. If you already control one battlefield and are at 7 points, you cannot immediately win by conquering the second battlefield because you would need to also score the battlefield you already controlled that same turn.

Sequence:

• If after scoring the newly conquered battlefield, the opponent opens another showdown, you can ride the wind to the location you originally controlled
• Score that battlefield for the final point and win
• Alternatively, if you have another unit in base, you can immediately ride the wind it to the battlefield you originally controlled, which will trigger a second showdown there once the first showdown resolves

Nuances:

• A battlefield can be scored multiple times in a turn by different players
• A battlefield cannot be scored multiple times by the same player in a turn
