kinda crazy this ideia i had but sinse your in jail you can try it
see in TC map ? you can kill a player if you
1- 1 hit kill him
2- he stands near enohf to a guard that you pk with a multi targuet skill like rage ( think hercules or fire circle dont work )
soo.. my ideia is get some noobs to bootjail and but them side to the guard and then 1 hit kill then and voila your black name and your heading to jail
i never tried this trick its just a ideia of my own so dont flame cus os this
i hope it work with you and if it worcks let me know
