Tenacious

You have trained your body to recover quickly, giving you a remarkable endurance. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• When you take the Dodge action in combat, you can spend one Hit Die to heal yourself. Roll the die, add your Constitution modifier (minimum of 1), and regain a number of hit points equal to the total.
• Whenever you finish a short rest with less than half your total number of Hit Dice, you regain one spent Hit Die.
