Ardent Sacrifice (献身, Kenshin lit. Devotion) is an Assist skill introduced in Fire Emblem Heroes.
A unit with Ardent Sacrifice can interact with a wounded ally. The unit with Ardent Sacrifice gives up 10 HP and heals their ally by the same amount. If the user has less than 10 HP, they will sacrifice as much as they can while leaving them with 1 HP. Hence an Ardent Sacrifice unit with 7 HP will heal their target by 6 while they retain 1 HP.
