Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General New talents? Ambidextrous and Living Armour

That's not what the talent description of Comeback Kid says, in the EA at least. If you get a mortal blow, it revives you with 20% life.

In one of the late videos one of the companions had Unstable and Comeback Kid visible as talents. Either the testers at Larian expect to be killed several times or Unstable works before Comeback Kid. The latter would be a reason to take the combi, it's still situational, but nice.
