If you've ever played Minecraft: Story Mode and thought "i wish this was actual minecraft" this modpack is for you:
Not only does it add the Wither storm, but also dungeons to easily gear up as well, along with the proximity voice chat mod and some optimization and tweak stuff
If you don't know anything about the wither storm, go check out Cracker's Wither Storm Mod and read through the description or something idk
also WTHIT if you're into that i guess
maybe some JEI
and other cool stuff to make life easy
i suggest you start a new life in the end or nether after summoning the witherstorm cause man oh man will you regret your every life decision
oh and i suggest you use a pc with a good graphics card unless you wanna fry some eggs on your computer
k thats it
