The weapon Fist of the Damned, dropped by Ogom the Wretched has a life drain proc. This proc chance isn't very high (10 times in 5 mins), but it scales with SP. You may say this is intended, but you can get some really nice hits (7k'ish non-crit) with this thing at 85. Also this could be a pretty cool heirloom'ish offhand.
