It's a pack of varying vampires, with some being broken to jaw dropping extents!
(dw those ones are optional, I mean technically every one is if you modify it but still)
there's 20~ I think? most have some sort of unique part of them, or immunities/abilities, generated via the generated vampire script (I'ma double check to make sure this is the right one later I'm rushing to do this rn)

But yeah Uh I'll make a post describing them sometime soon, any bug reports will be dealt with as soon as I can (school+work kind of can get in the way of that)
