Highly recommend to set memory to 8GB, or you might getting crashed!!

There are so much mods inside that I will mention about 5 main categories:

1. RPG Adventure

I put many RPG style mods in it. Like Lootr makes everyone loot chest are not the same. And more give enemies some buff to make them getting stronger. 

2. Magic

Ars magic are the main mods and have even more that you can play with

3. Engineering

Immersive engineering and thermenal are always the best to let you play the engineering

4. Dragon

Ice and fire. Dragon Mount. And draconic evolution are the most difficult mods.

5. ProjectE

Cause the mods above are too hard. I added the most powerful mod ProjectE to let you play a little simply(very little)
