>Defeating Gollux on any difficulty will result in the same rewards.

I'm planning to start killing Gollux in the near future, what level of drops is he giving?

I don't know why it says that, to my knowledge this has never actually been the case. Maybe people were confused because higher difficulties can drop the lower difficulty equips? (And that's perfectly fine if you ask me)

But to answer your actual question, His drops range from level 120 (or was it 110?) to 150. He has 4 difficulties that vary depending on how many of his different body parts you destroy before fighting the head of the body.
