-This guide is basically COMPLETE-
Introduction
Well, hi there! Welcome to my Yoyo Acrobat guide.
I take it you want to try killing stuff with the fabled Yoyo. Whether you go Yoyo Jester like most of us, or want to try Yoyo Ranger just to be different, it doesn't matter. You'll have to go through Acrobat-hood either way. What's that? You don't want to use a bow to speed up the process? All the more power to you, my friend!- but that means you'll have more torment too. Which is why you're here. This guide will help you make it from level 15 to 60 by sharing with you good strategies, useful armor, deadly Yoyos, and much more.
A few more tidbits:

Prices for yoyos, armor, and some jewelery are located in the Equipment section. If you know of a price that needs to be added or updated, be sure to let me know!

Guide is written by me except where it says otherwise.

If there's something that you think should be added, please let me know.
