For those who are unaware, Lethal Mark as it works now has a debuff that can never be reapplied to an enemy player after the first throwing knife hits.

In the video you'll see that the skeleton shows the Lethal Mark icon on the first throwing knife. Any subsequent knives will NEVER proc lethal mark on the same target again.

It's not a matter of waiting either for some type of cooldown on the debuff, it just doesn't work.

P.S. Ironmace, Dual Strike should unsheathe your weapon for you on use. The decrease in wind-up time this patch didn't help the ability.

Has any one tested whether Mobs are always considered out of combat for Sneak Attack proc?

When testing on a dummy, the dummy is always out of combat even after attacking it multiple times.
