What is the chance of looting the Forbidden Fruit?

Question

One of the bosses of the Forgotten Knowledge Quest is supposedly dropping this item.  What are the odds of looting it? 

Answer 1

I honestly think it has to be considered very rare which would be less than 0.5%. I cannot verify the percentage or the category the Forbidden Fruit is under, but it would only make sense. This item is super rare and not a lot of people own it. I personally don't have any experience in looting this item myself.

Yes, the chance seem to be really small. I remember doing it with my team countless and neither I nor my teammates looted it.
