Healing Factor

You gain a healing factor allowing you to recover from any injury. You gain the following benefits:

Hard to kill:

• When you succeed 3 death saving throws you are revived with 1hp
• When you fail 3 death saving throws you do not die, but are unable to be healed and are unconscious, but in 1 hour are revived with 1hp.

Regeneration:

• During combat you heal 1d4 per turn if you are not downed. 

Careless Fighting:

• All attacks against you have advantage.

Overpowered? Probably. Fun? Absolutely. You are now Deadpool or Wolverine.
