It is not a target. It is a warning to the mages.
Some of them quit. Some of them keep invis up. Everybody knows that you will get truesight on 25. And if you do not have it invis will save, cause you not use potions (if not a svirf or assassin)/.
They begin to spam where like "cast something;where". As mage I even had an alias on 'c' - "cast %1;where".
They add colors on known villagers. And thank's to the title they will know you a villager even after you inducted.
You a target only for the really cook PK profy mages. But for those players anyone is a target. They often go Scarab so they gather those kills anyway.
As you get the title the challenge is not "to survive". The challenge is "how to find a mage, sneak up and hit him" with 10 players online and one mage in PK - this challenge is real pain.
