Thanks to https://www.planetminecraft.com/member/themcoder/ for inspiring me to make this boss fight.

This is a map, and I don't know if I will make a datapack version in the future.

Be careful, the boss does a custom attack every 15 seconds, which goes through shields.

Press the button under the barrel to restock. Leaving or dying during the fight will spawn another boss when you enter.

How to play: Just take the folder out of the zip and put it into your .minecraft saves folder
