Life Domain: REACTION - You and one other creature within 25feet regain all lost hit points.

Weekly Mighty Domain, WMD [Use your reaction at the end of an allies turn] As a hero and a devout follower, your deity grants you a special mighty feature that you can use once a week. This feature is called a Weekly Mighty Domain (WMD) and once used can’t be used again until you have had 7 long rests. Which feature you may perform depends on the domain or domains of your primary deity. If they have more than one domain, you can perform any of them, but only one per week
