Job/Sub job -- How?

[Grafnir]

Ever since I started playing (and especially since I got on Ragnarok) I've been seeing people with jobs AND sub jobs. I knew they existed, but I didn't ever learn how to have the two jobs at once.

So, how can I get a sub job? I'm a warrior right now, but I'd like to have the sub job of black magic.

I know this is a rookie question... but hey... I'm a rookie!

Also, I did look in the archives for this question, but there are around 40 pages that came up, and I didn't search every one of them... sooo... sorry if it's been asked before.

You have to be level 18 to get a subjob. I think you have to do a minor quest to go and get it.

You have to get ur warrior to level 18, then go to the NPC that gives you the Subjob quest (info is on the main site shoulda looked around there first...) then, im not quite sure how to equip them. But, im sure its under the Subjob quest section of this site
