Hello, I was gonna wait till I had 3 questions but I couldnt wait ^_^

okay easiest question !

I figured out what slow does...so what does heavy do? its a new effect I'm not too familiar with...

and the complex question!

additional skills...I know that classes can use them...but can jobs? I thought that jobs couldnt equip them...but I've been reading posts in the forums and for some reason (can't remember what has made me think this...) it seems like jobs can use the skills from other classes?

Idk, any answers are appreciated ^_^ thank you
