It took a while getting there, but PvP gear finally made it to Age of Conan. Was it worth the wait? Apparently, yes. The PvP patch has caused a marked increase in enthusiasm for the game, and players are killing each other like never before in their haste to earn PvP levels. Unfortunately, the AoC PvP notoriety patch didn't go live yet, so nobody is being branded as a murderer or criminal no matter how many lower level passers-by they ambush and massacre.
Martuk at Ten Ton Hammer has put together the first part of an exhaustive catalog of all the PvP gear that's made it into the game so far, complete with requirements and bonuses, so you can plan out exactly what you want to wear in your PvP career. You can pick the gear up from vendors, who you can find in the game's racial hubs.  Each piece has a minimum PvP level required to wear or wield. Note that the minimum character level is 80; this is definitely endgame stuff.

Although there are ten PvP levels, the gear available only goes up to level 5 so far. More gear will be coming in the future to take the system all the way up to level 10.
