Mercy is a powerful ability in the game, and it can be used to heal allies or yourself. However, there are a few things you need to know in order to use Mercy effectively. First and foremost, always aim for the head. This is because Mercy deals damage over time, so if you hit an enemy too often, they will eventually die. Secondly, try not to use Mercy on enemies that are already dead. Doing this will result in them not healing any further and may even cause them to die. Finally, make sure that you have enough health points available in order to use Mercy effectively. In most cases, it is best to spam your abilities until you have at least 50 health points left.
