Jokes aside, this would be a pretty sick addon for Vampirism
I wouldn't presume it too hard to convert, as older mods (1.12) have used similar stand systems, though the visual effects you've got are very nice.

No worries if not of course, I'm working on my own JoJo mod for 1.16, its just gonna take me and a friend a while and having some stand powers now would be fun, lmao

keep up the good work, though! glad fabric has good options
