Tempered Iron
Reaction
Digging within, you stave off the call of death and surge renewed towards your foes.
When you are reduced to 0 hit points, you can use your reaction to heal a number of hit points equal to your proficiency bonus.
If you were reduced to 0 hit points by a spell, you instead heal a number of hit points equal to your level. In addition, for the next minute you gain advantage on attack rolls made against the creature that reduced you to 0 hit points, and your weapon attacks against it deal extra damage equal to your proficiency bonus.
