Biome conduit

Similar to the ocean conduit, the biome conduit can be placed and surrounded by a unique set of blocks to be powered. The type of blocks you put around the conduit will determine what biome will be created. For each biome, there will be a different set of blocks needed. 

Example: surround the conduit in sandstone and it will change the surrounding area into a dessert.

I think everyone has been in the situation where you built your base in a biome that you regretted. using the biome conduit will allow the player to customize what biome they are in after they built the base. It can also be used to mob proof your base by changing it to a mushroom biome. 

Many think Minecraft has a lack of unique loot tables in the chests. most loot is the same in all the randomly generated structures with few exceptions. adding the biome conduit will also help solve this problem.
