As an reaction, If a creature that you can see with 30 feet of you is hit by an attack you can choose to take the damage (this damage can not be mitigated and ignores temporary hit points) and if you do the creature takes no damage and gains temporary hit point equal to half of the damage. These hit points last one minute.

A Solider as Well

Starting at 6th level, when a ally with 5ft of you and is attacked by a creature and would be downed, you may make a melee weapon attack against the creature that downed them. Your ally is reduced to one hit point instead of zero and half of the damage you deal from your attack is returned to your ally as temporary hit points. These hit points last for one minuet. You may use this feature once per long rest. This increases to two times per long rest at level 12 and three times at level 18.

Comrade in Arms

Supreme Healing

Starting at 17th level, when you would normally roll one or more dice to restore hit points with a spell, you instead use the highest number possible for each die. For example, instead of restoring 2d6 hit points to a creature, you restore 12.
