AdventureQuest Worlds Tips

To make this work you need this:

Grumle's Curse Axe with a high enhancement (you get it if you fight Grumble a few times)

So after you get the Axe from Grumble at the Sewer, buy a high enhancement. (about lvl 12)
Then sell it for more than 2,500 gold.
And voila!
You'll have lots of gold to buy weapons and pets!
