Do you need to capture both battlefields in the same turn to win the last point? Or if you had one already coming into your turn and capture the second does that count as 2 points in 1 turn since you held and captured?
To win the game by scoring your 8th point, you do not necessarily need to conquer both battlefields in the same turn. The requirement depends on how you earn that final point.
According to Rule 448.1.b and the associated RiftJudge FAQs, here is how it works:
- If you win by "Holding": If you already control a battlefield at the start of your turn, you score a point for "Holding" (Rule 446.2). If this point brings you to 8, you win immediately. You do not need to conquer the other battlefield.
- If you win by "Conquering": If your final point comes from a "Conquer" action (Rule 446.1), you must have scored on both battlefields during that same turn to win.
Addressing your specific scenario:
If you start your turn with 7 points and you already hold one battlefield, you will score your 8th point for "Holding" at the start of your turn. You win immediately the moment you score that 8th point. You do not need to capture the second battlefield to win.
As stated in RiftJudge FAQ #4982:
"If holding a battlefield at the start of your turn gives you your 7th point, can you then capture another battlefield that same turn to score your 8th point and win? Ruling: Yes, you can. You need to score all battlefields on the same turn only if you want your final point to come from a conquer. Holding counts as scoring on your turn."
Summary of the rules:
- Rule 448.1.b.1: If you score through "Hold," you score the final point.
- Rule 448.1.b.2: If you score through "Conquer," you only score the final point if you have scored every battlefield through either method (Hold or Conquer) that turn.
In short: You only need to conquer both in one turn if you are using a "Conquer" action to reach your 8th point. If you reach 8 points via "Hold," you win immediately regardless of the status of the other battlefield.
