Does anyone have the Combat medic perk in Fallout 4? It's supposed to heal 100 HP if the players health is less than 10%. But how does it work? Does it have some inner cooldown, and if so how long is the cooldown? Is it something you have to use, or is it automatically activated? Does it heal over time, or is it instant?
It takes a while to get the companion perks, so I'd rather know what it actually does before I invest the time.
