This mod is made with MCreator, so don´t expect anything super profesional.
This mod adds a block wich produces a gas column that can make entities levitate upwards.
The way it works is the following:
The gas block will apply a levitation effect as long as the entity is touching the block.
So, you can use to go up like the 1.13 bubble column or you can use it as a infinite lava farm.
The block generates in the Nether, around y=32. When is not activated, it will emit thick smoke particles.
You can use in your packs, but please credit me.
Hope you find it useful. =)
