"Boost : " is a keyword that represents two powers. The first power means "To play, you may pay ." All boost costs are expressed in resource points unless noted otherwise. The second power varies by card type; - For a character card, the second power functions while it's in play, and means, " is active only if this card was played this turn and was paid for it." - For plot twist cards, the second power means, " is active while this effect is on the chain after the intention to pay has been announced until this effect has finished resolving."
