I like to use Claws of Ahamkara for pvp, probably not a popular choice since void is preferred by most. But a well place tripmine, still one of the best kills in the game. also proximity knife (but I use it like another tripmine) with Gunpowders gamble - which is just the best!! there is a build where in PvE you can have infinite throwing knives so long as you get the kill with it, quite fun
