Your battle-hardened body recovers more quickly than others. You gain the following benefits:

• Increase your Constitution score by 1.
• You have advantage on death saving throws.
• When you have fewer than half your hit points remaining, you can use an action to spend two Hit Dice and regain hit points as if you had spent and rolled those Hit Dice during a short rest. You cannot spend Hit Dice this way again until you complete a long rest.
