As you play the game, you may hear others use the term "Reviver" or "Suicider" to describe a certain player. What this means is that the player they're referring to does something special in the game when it comes to battling. A Reviver is a player who has auto revive turned on all the time. That means that you can kill them as long as they have sufficient herbs to full heal, because they'll just automatically revive. If you are looking for a lot of people to attack and kill, it is best to have a list of revivers at hand so that you always have players you can attack. The only thing revivers ask in return for their services are blue herbs and healing herbs so that they can keep reviving. If you see that a reviver is dead, it is more than likely because he is out of herbs.
