I got every trophy that I need, except the "Enraged Aegror Bunion".
I killed many of them(around 7), together with Luna, and never found one. The rest of the trophy were found after I killed 1-3 monsters of each kind for the quest.
I don't know why I don't get the Bunion but I would like to finish the quest. Maybe it's a bug or I am just unlucky
[EDIT]:
By the way, my char is Draa Gul.
