Wave Imp Evolution Quest

In the ancient bronze wyrm area, find the the Bronze Wyrm. You can't enter the room with Vincent without killing the wyrm because the lever needed to open the door won't appear until the Wyrm is dead. Use an alt or ask a friend, it's pretty big and it tails/breaths (obviously). Go north after you pull the lever. You'll find Vincent and all you have to do is listen to him talk, when he has finished talking give him the scroll you got from the MNI quest, listen to him again and then you can evolve.
