i dont know if anyone requested this but i would like to request the most puzzling mod there is, Thaumcraft, due to research being puzzling, i find it fun

Thaumcraft is a mod about magic and aspects, the way aspects are made is the part that add the challenge since you link them up with what makes them or what they make in the research
