Undaunted Clutz (SH)

Not only are you unafraid of failure, you are heartened by it. You gain the following benefits:

• Increase your Constitution by 1, to a maximum of 20.
• When you roll a 1 on an attack roll or ability check, you gain temporary hit points equal to your Constitution modifier.
• You often injure yourself by attempting physical feats overeagerly. When you make a Strength or Dexterity check, you can give yourself advantage on the roll. If you do this, take 1d6 bludgeoning damage. You can use this ability a number of time equal to your Constitution modifier, and you regain all uses after a long rest.
