This is a little engine which allow you to set all those ranges (and its respective color) of pvp or pks as you want.
The engine loads from database all ranges and his respective colors at server start up.
You only have to fill the database table as you want, following this structure
pvp count needed, range color, range type
50, FF0000, pvp
Note1: the range type can only be setted as pvp or pk
Note2: it come with some ranges, but you probably will find them crappy :D
