You spawn in a normal Minecraft world and can explore many dungeons such as guarded aircraft carriers or wizard towers.
You can also be a wizard to shoot fire, create shock waves or summon an army with your wand.
You can build your own power farm to generate energy, make powerful weapons, and dominate the Minecraft server.
You can also craft powerfull nuclear rockets, track your friend's house and explode all of it.
I would prefer 6GB RAM and render distance max on 24 to play this modpack with 100 Mods without any lags.
I would also prefer to add Optifine to the modpack, but because of the curseforge terms you have to do it yourself.
But I still hope that you enjoy playing this great modpack. Have fun!
