Nine Lives

You've always managed to stay one step ahead of the scythe of Death, and gain the following benefits:

• Increase your Dexterity or Charisma score by 1, to a maximum of 20.
• You have advantage on Dexterity saving throws while you are below half your hit point maximum.
• When you fail a Death saving throw, you can choose to succeed on it instead. Once you use this ability, you cannot do so again until you finish a long rest.
