Seven Hit Points
One failed death save. One bonus action. Seven hit points between alive and dead.
Theren has failed his first death save. The ogres are right there. Elaris sprints to within 30 feet and fires off Healing Word - just a bonus action, just a few words of power. Seven hit points flow into Theren. It's not much, but it's the difference between alive and dead. He's back on his feet before the next swing lands.
