Unyielding

Whether you've trained for life-threatening situations or had a blessing bestowed upon you by a deity or otherworldly entity, you gain the following benefits:

• Increase your Constitution or Wisdom score by 1, to a maximum of 20.
• When you make a death saving throw, you regain 1 hit point on a roll of 19 or 20.
• When you or an allied creature within 30 feet are brought back from 0 hit points or use a feature to drop to 1 instead of 0, you gain a d6 Unyielding Die. Whenever you roll to determine damage or healing dealt, you can expend one Unyielding Die to roll it and add it to the total. You can gain a maximum of 3 Unyielding dice per day, and lose all remaining Unyielding dice when you finish a long rest.
