Firebolt Dan Ranking

Does anyone know how much AP it takes to rank up the Dans? (Firebolt specifically.) If you know any, I suggest working on a table to put on the page that explains the amount of AP required.

Lol....0 ap. It's just a special title added to the front of the master title. It doesn't give any increase in dmg or stats therefore it takes no ap.--DANTE20XX 11:17, 4 April 2011 (UTC)

Uh, they do take AP. 7 for 1st, 10 for next, 15 for the last.

Is it tested to prove that all skills require the same amount? If so, then we should include this into the page. I am sure others have had this question before and will have it later on.

JP wiki says it's the same for all.
