I've played the Demo of this game and I'm currently playing a duo with my bf, and we have come across a debate. To put plain and simple: is there a limit to how much Power a player can spend to create a status? What is stopping them to simply spend 3 Power to cause harm-3 on a Challenge, potentially "one-shoting" it? How do you guys handle that situation? What am I missing?
