The apocalyptic bucket is currently only used for crafting stuff, if you want to be like my avatar you can try wearing it as a hat but it would probably not work.
Tsunami Bucket (aka classic bucket)
The tsunami bucket creates a water-like substance that moves faster, spreads infinitely, and can sometimes break blocks. If you place it on the ground it floods the area and creates a lake, if you place it in the sky then it would flood the entire world with a wave of water.
Mask your world with darkness, darkness so dark it has the same properties as lava but spreads forever and can also flood areas.
It creates green fire that will spread forever.
Creates a BlackHole. Well actually it isnt black or a hole, its just something that sucks in other things and changes form. If it doesn?t do anything thats cuz it slowly grows in pick-up radius so you have to wait 2 seconds.
none, and besides it would look a lot better in video
Creates a flood of toxic water that kills players and turns everything else into zombies, useful for post-apocalyptic scenery.
