Gunslinger Build (Lv. 10-200)

Rapid Fire is a terrible skill, For a bossing build Max Ship > Max Bullseye > Max RF would probably be better.

And where did Max ship go? I"m guessing this guide must be really outdated if it doesn't have max ship, which helps both in training and bossing.

You gotta remember that this was written before the kmst skill updates and back then max ship was a bad way to go. Now, Max ship is probably one of the better things you can do in my opinion.
