A card's skill can be a passive effect that is activated automatically when the card is played (an Instant skill) or something that must be activate during your turn (a Manual skill). You can only use one active skill during your turn. The player who must move first in a round has the final chance to play a skill after both players have used up all three turns. Skills can only be used from cards in play, and not from those still remaining in your hand. They can be activated during your turn, before or after you play a card. For example, the Traitor card features the Betrayal skill. This allows it to switch places with the opposite card in exchange for changing its Risk to 2. The Fire Scout has the Revealer skill which shows the elements of the cards remaining in your opponent's hand.
