Wither Storm

I really love the wither storm from minecraft story mode i think it would be great to have but i think it needs to be changed the command block at least you should adventure to get like a conduit, sulk catalyst, nether wart, shulker shells etc and combine it into a heart block so then in order to make the wither storm you have to venture around the world or if you want to play it off spawn make a toggle able switch to to spawn in a structure so you can access it off spawn but if you want it in your world you have to actually explore the world and find rare structures and biomes in all 3 realms in order to craft the heart of the beast. For the wither storm i think it would look cool with a tornado starting from the bottom of the main wither storm it could have lightning attacks as well.
