About this Mod
This mod adds 2 blocks:
- Random Lucky Block
- Random One Block
The difference: The one block regenerates, the lucky block doesn't
Fully compatible with other mods, also using modded items in the drop pool.
I recommend adding a bunch of other mods to make the challenge more interesting
IMPORTANT!!
To create a OneBlock world:
- Create new world
- Select Superflat
- Go to presets and select Void world
- Go to Game rules
- Set the game rule generate OneBlock to true
