I had Burne in my party when I found the golden skull. He didn't leave because I stole it with my rogue, and Burne didn't see. Then I let him leave at his temple, told him about the skull, then got him back I think, and then his assistant demanded the four items: gust of wind, fireball, holy water and masterwork maul or what it was called.

I have them, but she won't accept. What gives?

I am only at dungeon level 4, the gems from the nodes are NOT inserted.
