My friends and I would like to play a modded world together now that we've found 'The Essentials' mod which allows us to circumvent our previous issues with multiplayer. However we've had some issues with finding good modpacks. None of us are experts so we've just been trying ones we've found.
We've mostly tried 'Create on a Potato PC Ultimate' and 'Create: Arcane Engineering'. Create on a Potato PC was/is great but we have a minor crashing issue. Arcane Engineering integrates the mod so much it makes trying to primarily work with one frustrating. My friends have also tried Create Chronicals and found it to just be altogether too much.
What we're looking for is a pack with Create (addons desired but not needed) and an in-depth magic mod like Botania or Ars Magica.
It's not a part of the "Create" series of packs, but Better Minecraft is essentially just a gigantic overhaul of how the game works. It has things like The Aether, Twilight Forest, as well as BetterNether and BetterEnd iirc.
