How do you get all the spells in the game murloc

Save your game. Go into the portal, then click load on the title screen. You'll notice it says 'Darkmoon Faire' as your location. This is a kind of reward for finishing the game. You can buy spiced wolf meat and magic dust from the first goblin you see (He looks like Grahko) and enter the 'Darkmoon challenge' at the second. The challenge takes you through almost every enemy in the game and a bonus one at the end. he is level 60, has 6900 health and a mean punch but most of the time he just flexes his muscles. Beat him and you get this uber-powerful weapon. You can fight him again but beat him in one round when before it probably took you 30. Then save and load to start the challenge again. The weapon the guy has is worth a lot of money. You can still level up and get talent points for spells and skills though.
