This most likely isnt possible but i just thought of this role the Attacker. The Attacker can take a life (or only attack the player a little not fully killing them) from a player and only a medic can heal and make the missing lifes (or the little attack) that they had back all roles will be notified that they got attacked from the attacker but it wont stop any abilities however if it catches the medic it will make the heal not work (kinda like witch but only for medic) if there is a savior, then the savior ability will not work if they try to bring someone back to life if the attacker gets them.
