Challenge Advancements

This Datapack adds thirteen advancements (two of which are hidden).

The advancements can be found in-game under the 'Challenge Advancements' tab with the green book:

Each advancement comes with a reward banner as a sort of trophy, these banners are not craftable in vanilla survival due to having more than six layers.

The reward for the 'An Acquired Taste' advancement is a Bundle containing Music Discs with songs which you can't normally play in a jukebox in Survival. (including Alpha, Chrysopoeia, Dragon Fish, Wet Hands, pokopoko & more).
Due to technical limitations I can't put each individual song on it's own disc.
This Datapack uses the jukebox_song experimental setting, any custom Music Discs lose their sound events (which is what makes them play different songs) when the Datapack is uninstalled.

Roadmap:

• Backport at least as far back as 1.18
