Indomitable Spirit

Your unshakable spirit and ability to resist the overwhelming force of your opponents has given you the following benefits:

• Increase your Constitution or Wisdom score by 1, to a maximum of 20.
• When you become stabilized by succeeding on 3 death saving throws, you immediately gain 1 hp and become conscious.
• As a reaction when you fail a saving throw, you can expend a hit dice and gain a bonus to the result equal to the number rolled on the die. Additionally, your current hit points are reduced by the amount rolled plus your level. You can use this reaction after you know if you would have failed, but before any effects are applied. Once you use this reaction, you may not do so again until you take a long rest.
• If you are subjected to an effect that causes you roll a saving throw on each subsequent turn after the effect takes place and fail the initial saving throw, you may make each subsequent saving throw with advantage.
