[@Xavier Bloodbayne]

I had to get a bit tricky there to find an opening! But, I'm pretty sure it'll be a mutual kill. Keep in mind that Auz has a ridiculous, ridiculous tolerance for pain. He is hundreds of years old, and most of that time was spent getting mutilated on battlefields and killing himself for power. He tried to lasso Xavier with his own lower intestine, after all.

If it's a matter of Aux going into shock, that won't occur until his brain registers the blood loss, requiring a few moments of circulation to occur. Some of his abdominal muscles also may be compromised, but consider how Xavier is basically being held in place by the sword. There's no way for the already insane stabbing force to dissipate by way of his head being shoved along with the direction of the attack.

And then, there's the weapon itself. The stiletto is like a reinforced, devilishly sharp ice pick, pretty much made for shanking things.
