Quick characters have lightning-fast reflexes and a cool head. Whenever you are dealt a 5 or lower in combat, you may discard and draw again until you get a card higher than 5.

Characters with both the Level Headed and Quick Edges draw their additional card and take the best as usual. If that card is a Five or less, the Quick Edge may be used to draw a replacement until it’s Six or higher.
