Satisfying One-Hit Ender Dragon Mace Kill

I DID THIS FIRST TRY!!! I would highly recommend trying this (it's really satisfying to do yourself), if you have good timing :) Note: The 'At the Rim of the Sky' advancement is not vanilla; it's from a datapack I was using called BlazeandCaves. Also, due to directional audio, some sounds may sound quieter. Apologies for this.
