Hello!
This is a plugin request for Newer versions of Skript.
On Bukkit.org this plugin support 1.8.8 and older versions.
The creator of this plugin publish this plugin on GitHub for Newer versions of Minecraft.
I know that this plugin isn't on Spigotmc or Bukkit.org, but this is just the same plugin, just a newer version.
