Indefatigable Body

Your body is unwavering in its grip on life, even when your mind cannot be. You gain the following benefits:

• You gain proficiency in death saving throws. If applying this bonus to a death saving throw increases the total to 20 or higher, you gain the benefits of rolling a 20 on the d20.
• When you suffer a death saving throw failure, you may choose to forgo this failure and gain a level of exhaustion instead.
• When you take damage while you have 0 hit points that equals or exceeds your hit point maximum, you suffer two death saving throw failures instead of instant death.
