So, this has taken me ages to figure out, because whoever coded this shit was probably deranged, and trying to track down the sound files that are ACTUALLY USED was an effort and a half, but it's done! Finally!

This is really just a sound-replacer for the death-noise so it's not a very complicated mod. Do let me know if you found any sounds that I missed, because considering how they'd been hiding them, it's not impossible that something slipped by me.

Making of the mod:
Originally, I just replaced the clearly labeled "Riekling Death Sound" wav-files with silent sound. This didn't work. I looked it up in the Creation Kit and found a "Riekling Death Sound" audio-file that used all of those files, and which in turn wasn't used by ANYTHING else.

Went digging even further into other creatures' death-noises to see if this was normal, and found a constant reference to "dialog"-files. Tracked down the "Riekling Dialog"-file and found that it had its own "death"-part, which referenced entirely different and completely unlabled death-sounds. Tracked down those files in the folder, was forced to download a ".fuz unpacker" to get access to them, listened through ALL of the files in that folder for the distinct "death noise" (since the names didn't seem to match up with what the Creation Kit called them), and replaced those files with the silent wav-file and then repackaged them into .fuz.

Decided to also keep the "clearly labeled" silent sound-files included in the mod, because... redundancy? I guess? It works now, so I don't want to change it back, and it's not like it hurts any.

In other words, this was a massive pain in the ass to do in comparison to pretty much any other sound-replacer I've ever found. But it's done now! So, cheers! Hope you enjoy.
