Trying to Master Mage Talent

As the title says, I'm trying to get to lvl 15 (Master) Mage talent and am having a very slow progress right now at the moment. Currently my Giant stands at lvl 12 (Great), and I'm trying to find a much more efficent way to get Master without having to spend too much AP (as the mage talent is the AP hungry **** as it it).

I've already r1 a majority of some of these skills but here's what I haven't finished/started yet. R9 Meditation R8 Potion Lore RF Shock Wave R5 Lightning Mastery RC Enchant R8 Fusion Bolt RA Thunder RA Blaze R8 Ice Spear RF Hail Storm

I've done the math on Excel and the most I need is about 824,400 EXP, but as I said, I'm trying to find the most AP efficient way to go about this. So if anyone has any ideas on what I would be grateful.

This isn't really the place to discuss such thing, it would be better to go to a forum.
