The Block Zones modpack is combination of a map and using the blocks from the Block Effects (1.8 version) & Alchemist Infusion (1.16.2 port) mods to show off the block time limits, and strength of potion effects added by the mods.
There is now a 1.16.2 version that keeps the idea of the 1.8 version but by using the Alchemist Infusion mod instead of Block Effects.
There is a map included to experiment with the mods.
