Works in 2.3.1.
Did it on my rogue, took 2 clefthoofs, I hit sprint and got around the corner with 200 health, went out of combat, ate, and I'd go in and out of combat every once in a while, ran out and shot him, even when I went out of combat his health didn't regenerate, had him at 98%, he died after about a minute.
