It turned out that the tunings for the vampires didn't have any coded responses to the sun buffs or timer beyond playing some annoyed idles. What this mod does is to fix the issue of vampires not doing anything to save themselves when they're burning in the sun.
This one has actually been up on curseforge for a little while now, I just kinda forgot about posting about it lol. I made another mod too self-preservation for the poor vampires!
