Where you can find the enhancement items in aqworlds?

When you login into AQ Worlds, you pick a server. They immediately put you in battleon. On the left side of the screen, there is a column of red buttons. Each one says something different. Near the bottom of the red button column, you will see one that says "Enhancements". Click that button and you're on your way!

There are also other places that have people who sell enhancements but there are too many to name...
