If you’re not happy with the outcome of a roll, you can choose to spend energy to improve your result. This is known as boosting a roll. Each skill is associated with an ability score, which is broken down into two categories: Grit and Nerve. Both have a boost score that determines how much each point of energy improves the result of your roll.

For example: You have a Nerve of 2, and make a [Reflex] skill check, rolling a 6 with your die. Normally, this would mean you receive a Full Consequence. You decide to boost your roll to get a Success at Consequence, but to do so, you need to improve your total result above 8. With a Nerve of 2, two points of energy are needed to boost your roll to a total of 10, giving you a Success at Consequence.
