Venenum

Just because your assassin temple doesn't get as much screentime as the super snipers, morphing ninja infiltrators, soulless psyker hunters and screaming junkie berserkers there's no excuse to stop looking boss .

Venenum Assassins specialize in poisoning people (their name is "venom" with extra "en"). Games Workshop doesn't seem to care much about them (probably because "I poisoned the well and caused your entire army to get sick and die" doesn't translate well to game rules).
