Runic Tattoos

Starting at 3rd level, your body is inscribed with the knowledge and power of your previous masters. This power takes the form of runic tattoos made from the blood of both you and your masters, infused with their ancient magics.

If during combat you take damage that would reduce your health to below half of its maximum (excluding temporary hit points), your runic tattoos activate. While your tattoos are activated you gain a +1 bonus to your attack rolls. This effect lasts until the end of combat or until your health is greater than half of your maximum hit points (excluding temporary hit points). Temporary hit points gained do not end this effect. The attack bonus for this feature increase to +2 at 8th level and +3 at 15th level

Also, your lust for the edge of death becomes a boon to you. When your Runic Tattoos are activated, if damage reduces your health to 0, you can make a Wisdom saving throw (DC 5+ the damage taken). On a success, you instead drop to 1 hit point. After the saving throw succeeds, you can't use this feature again until you finish a long rest.
