MabiPro: The Authentic Old-School Mabinogi Experience

So yea, I decided to visit mabi recently after years of not playing and use it as an afk game to play while I study. but there are some jarring things about it (chainswords) and doesn't seem to have the spark it once did. Currently downloading the client for mabipro and was wondering if there is anything in particular that should be known before delving into the game?

Thanks so much! I'll look over the links you guys shared with me. This helps alot
