COREBLOCK is a SkyBlock Type map that is seemingly harder than the OG Skyblock, maybe just a little but harder than Skyfactory, but thats just my opinion. Anyway, Most of this map is based around the Commands that allow you To custom Craft Recipes, which will indeed help you On your Goal…TO KILL THE WITHER >:D hehehehehehe….
Basically Your Goal Is to be able to kill the wither. You dont start out with much.
Note To Those who make it to Fighting The wither. Recommended to fight him in the nether, as you all have seen how destructive his power is…dont wanna end up getting your world destroyed by its heads.
