The procs on Khashek's Katar and Gold Inlaid Ulak, Claw of the Savage Lord, is a 75 point Lifetap. These weapons are upgrades to Zekha's Katar and Fist of Iron, which have similar but marginally lighter stats, and a similar proc called Claw of the Beast, which is 50 points of damage, but I can't drudge up any evidence as to whether or not these are Lifetaps as well. Can anyone confirm?
Aww, what a jip. I have all four of the weapons I listed, currently using Khashek's and Gold Inlaid Ulak, but if CotB isn't a Lifetap then it might not even be worth downgrading to those weaker weapons from 40-50. I doubt the procs would make up for the loss of ratio.
