PvP Advantage client

Hello, does anybody here know if there is a client dedicated to pvp hacking? Like a forcefield hack that only works in the normal radius so nocheat doesnt go off, a name tag indicator and radar? Not neccesarily a greifing client, but something that gives you a stark advantage during pvp. Something like that would be great.
P.S. A crit chance modifier would be cool also.

Best to use Griefcraft, since it has all three that you listed

As stated above ^ griefcraft has everything you've asked for.
