In some situations, you are limited to playing cards or using powers that affect or otherwise relate to the current situation. In these cases, the things you do cannot require anyone to do something else for your action to be meaningful-the things you do must directly affect the situation. For example, let's say that a character is attempting a check using a power that adds 1 to her check for each blessing in her hand, and a second character has a power that allows him to give the first character a card. He could give her a blessing, because that doesn't require any other action to affect the check. But he could not give her a card that can be played to draw a blessing from the vault, because she would have to do something else – in this case, play the card he gave her – to affect the check.
