I have the head of the female troll, 5x essence of death, 6x endraga embryo, eyes of the arachas but the quest indicator says that I have the 3/4 of the ingredients. Am I missing something or is it bugged?
Well it's not endraga embryo, but endraga fetus (which might not be the same thing) . Needless to say i've not found any "fetusses"
nor the eyes of arachas (and this is the bug i believe)
So i think there is some bug. Firstly when you fight the only arachas in the chapter, you get no chance to loot it!
It will cut away to a cutscene and you will be at a different place. When i returned there was no arachas body to loot!
also did not kill troll at first but when I realized that i needed trolls tongue and he was the only troll around I went back and I said "I change my mind: Die now!" and i took his tongue by force lol
There is another way to get a troll tongue , hint : the troll had a wive...remember?
Regardless, the fact that i couldn't loot the arachas = BUG . If Fetus = Embryo = another BUG .
