Diana Battle Mage rework concept

Just wanna make it clear this was just for fun so dont really care if its OP or even underpowered, i just really like the idea of her actually being the embodiment of a moon goddess so i went with kind of a battle mage sort of theme here.

Passive - Diana's Auto attacks empower her sword, after 5 attacks her sword will send out a line of moonfire that deals 5/10/15/20 flat damage.

Q Midnight Cleave - Diana winds up, and cleaves the area in front of her (think of second Aatrox Q) for 30/45/60/90(+30% AP)

W - Crescent Kick - Diana backflips a short distance and gains a shield that absorbs 20/35/50/65(+20% AP Ratio)

E -Purge the Shadows - Diana lunges forward impaling her sword into the ground and igniting the area in Moonfire that slows for 15% and deals 30/45/60/75(+20% AP) per 1.5 seconds.

R -New Moon - Diana becomes the physical embodiment of the moon goddess for 10 seconds , relinquishing her physical sword for Moonfire Swords that now burn her targets for 15/20/25/30(+10% AP). During this time her Q and W are now more aggressive and empowered.

Empowered Q - New Moon Cleave - Diana now slices the area in front of her with both of her Moonfire Swords, and sends out a shockwave of moonfire that deals 50/80/100/120(+30% AP)

Empowered W - Chase the Night - Diana now lunges forward, and gains a shield that absorbs 50/60/80/100(+30% AP)
