You know how when you look at the endermen they start a loud annoying scream? And when you kill them, they just proceed to keep screaming and give you a headache? Yeah this mod is literally just to shut those guys up after they die.
Upon death, any enderman stare scream sound effect just gets absolutely deleted.
This mod is highly optimized and has zero performance cost, and it works even if you have it only on server-side! Yay!
The mod's NeoForge version was not working for a long time, this was recently patched.
