Players resolve Fast Powers — both Innate Powers printed on their Spirit Panel and Power Cards they played. Powers may be resolved in whatever order the players want, so long as no Power interrupts another partway through. If a player discovers they do not want to use a Power’s text effect (or cannot use it), they may choose to skip it entirely.
Sometimes, a Power Card will be worth playing mostly or even solely for its Elements.
You can’t delay using a Fast Power until the Slow Phase, even if you want to. Use it now or forego it. You don't get your Energy back for foregoing a played Power card.
