Can I advance to 4th job if I don't spend all my previous SP?

I can't seem to find a solid answer on this by searching so I figured I'd ask here.
Basically, I'm a 11x Dual Blader and I never added SP into Tornado Spin because I didn't really find it necessary. So when I reach 120 and go to advance am I going to get some message saying I need to use all my SP? If anyone has a screenshot of this happening (or not happening and advancing as usual) that would be great. I'm just hoping I'm not going to be denied my advancement and have to either buy the book from CS or hunt down the non-CS book.
Thanks in advance.

Pretty sure you do, but I would add to tornado spin anyway. The actual skill is useless, but you can chain it on to the end of a flying assualter by pressing the attack button (Default ctrl) after you hit the ground, and it improves the distance you momb over significantly.

I do have to note you're spending more effort finding out if it might happen than it will actually take to just spend the SP on the spot if it does in fact happen.
Not like you have a 5 second window to successfully 4th job or lose it forever and the SP must be spent by that point or ruin you.

I see...well if it does help my training mobility perhaps I will get the skill.

Well the problem is that Tornado Spin requires a mastery book to max, therefore if I left the SP unused and then was unable to advance, I would have to go to the trouble of either buying the book from CS or trying to find one in Mardia's FM just so I can use up those SP. It's mostly just a big hassle.

Regardless, I think I'll do some surveys for nx or keep an eye out for it in FM while I work on getting to 120. Thanks for the responses.

Ah, that makes sense. Forgot the "Nexon is a douche" factor.

Yes, you do need to spend all your sp before making 4th job as a Dual Blade. And you don't need to put the points into Spin, I just put my extras into 1st job skills since they don't have any real use other than that.
