I did Hearts of the Pure quest. I don't rememebr if I did it before. But I did it at level 35 and turned the hearts into the guy in Undercity. I was supposed to summon a succubus and kill her. My reward was to be able to summon a succubus, something I accomplished at level 20.
When I turned them in, I got a level [36] quest called "the Binding" to summon a succubus with the "Pure Hearts" (which I got when I turned inthe "Hearts of the Pure" quest) and kill it.
I do summon the succubus and kill it, but I don't retain the hearts.
I'm guessing the quests are messed up, but just wanted to make sure I wasn't supposed to be able to summon a super-succubus with this quest or not.
