The Assassin’s Guild Disinformation and Slanderization Department
Basically, if your reputation gets to the Hero level, a bunch of assassins wearing your clothing and cosmetic items will start spawning throughout the War Seas, using whatever weapons or abilities you happen to use (Light Magic, Swords, Unarmed Combat, etc) to murder innocents, destroy property, and otherwise do everything a particularly sadistic player who has hacked your account and found a way to shut down the Renown Shield mechanics might do in order to plunge your Fame into the toilet and send you on a crash course with the ‘Warlord of the Sea’ positions on the leaderboards.
Worse, this actually works; every single thing these Assassins do results in loss of fame as if you did it yourself, and their bad deeds can and will get you mentioned in the Agora. And they NEVER STOP. Not even if you go to silverhold and reset your reputation. And have I mentioned that any of these assassins you manage to kill respawn daily? And by daily, I mean ‘Once every in-game day’.
Oh, and once you’ve gotten the Assassin’s Guild Disinformation and Slanderization Department sicced on your unlucky butt, any and all Assassin Guild Contacts you speak to will no longer allow you to reset your Notoriety, and will in fact react to you asking by pulling a pistol on you and instakilling you with a single shot.
