The magician

"Hello Lord Fred." says the old man. "My name is Belboz, the necromancer." 

"Necromancer? Do you do magic?" 

"Yes, I do. For a reasonable fee, I can do any magic that I know. Other magic will have to wait until I can finish studying this tome." 

"Cool!" says Fred. "How reasonable?" 

"Depends on how much effort it takes me to cast a spell." comes Belboz's reply. 

Fred thinks for a minute and…
 
 

1. asks the magician to cast a spell that would protect him from a dragon's breath. 
2. asks the magician if he would be willing to accompany Fred on his mission to defeat the dragon. 
3. asks the magician for directions to the Dragon. 
4. asks the magician to upgrade his sword. 
5. asks the magician to guide him. 
6. asks the magician if he can create a spell to kill the dragon from here. 
7. asks the magician to turn him into a dragon to properly fight the dragon. 
8. asks the magician to change him into a giant to step on the dragon.
