Designed to be used by people who want to play mod and people who want to stay in vanilla in the same server.
So the mod don't change a lot the gameplay and the world too much, except dungeon.
There is :
Alex's mob for some new creature
Create for a little bit of tech mod
Doggy Talent because dog are our best friend
Ars for some magic
Quark for some vanilla friendly tweaks
And to help to explore more easily, waystone and sophisticated backpack
With at least 4Go of RAM the modpack work fine
