This is a Skript addon designed to allow for full control over Advancements in 1.12+

Here is a well explained wiki of what Advancements are http://minecraft.gamepedia.com/Advancements

There will be more changes and features added in the future. The current Spigot build as of posting this, doesn't allow for player's to join the server. Also spigot is still doing heavy development on these features. More will be added soon.

All syntax except events are generated in a Syntax.yml that you can edit.
