All The Items is about collecting an incredible amount of resources. This is done on a 100% tech basis. Theoretically, no monsters have to be killed or anything like that. All items are craftable. Of course, mob farms can be built, but they are not necessary.
No matter if you want to play a normal world, superflat or skyblock. This is your modpack if you want to collect a lot of resources.
Of course, all raw materials can be obtained without mining them if you want. There are many different ways to obtain raw materials.
This modpack from the All the Items series has a medium difficulty. The recipes have been slightly modified to achieve some kind of progress.
