The quest named in title asks for Elixir of Demonslaying x 10, Invisibility potion x 10, and Elixir of the Sages x 5, yet does not show credit for Elixir of Demonslaying when they are in my bag, nor will the quest giver accept those specific potions.
Instead, when you look at the icon and mouseover the supposed “Elixir of Demonslaying” the Mixmaster wants, you see the tooltip and visual icon for Elixir of Giants, though the name still says Demonslaying.
So I went to town again, tried making 10 x Elixir of Giants, and go back, and that also does not work.
This was a very expensive quest. Please fix.
