Faction stones broadcast on a radius of 1500.

[LiamKarlMitchell]

Stone IDS are:

242 Guanin Stone 243 Fujin Stone 244 Jinong Stone 245 Yaoguai Stone

But I also wonder if these ones also have same radius. 333 Mangonel 446 Grace Juggernaut

Although, I think bigger boss monsters should broadcast for a longer distance in our server.
