It was fairly simple; the death sprite is a custom entity that gets spawned in lieu of the call to the "Make lots of smoke" function, and along with that I set it up to spawn like eight or so of those "blood drop" effects. I think I had to jump to some re-appropriated space to make it all fit though.
The difficult part was the blood drops, which is actually triggered by a TSC command that sets it in motion, and uses a global variable to time the appearance of each of the frames of animation.
