How many Morshabaal's Extracts are dropped by Morshabaal?

Question

I was wondering if  Morshabaal's Exctract is an unique item dropped by Morshabaal, like the Ferumbras' Hat or if it is possible to loot more that one Morshabaal's Exctract in a single Morshabaal fight.

Answer 1

It seems every single person who reaches the [participation threshold] receives an extract.
This is most people, who go into the room and help kill Morshabaal.
