Hello everyone!
Since the last topic about it, Elitemobs has pretty much received updates and is now 1.15 compatible!
https://www.spigotmc.org/resources/%E2%9A%94elitemobs%E2%9A%94.40090/
It also has a dev built on the website of the creator, which is also 1.15 compatible

I hope you add it real soon, because I'm excited to use it!
Sincerely,
Sarkness.
