The numbers on her skills seem a bit erratic with mana costs jumping from 50 to 150 and else.

And going by the numbers now, her Ice is broken: with maximum cooldown reduction it has a cd of 3.6 seconds at max rank and a radius that is bigger than amumus ult. And it knocks up enemies? At the cost of 1500 mana you can keep the enemy basically in the air constantly for 36 seconds.

Fire: These extreme mana costs are a bad way to limit this spells power. At max rank she'll be oom in 3 or 4 seconds, forcing her to return to the base a lot. Additionally, is that ap ratio applied per meteor? Does this mean by activating her ult and this skill, you get 400% Ap ratio at max rank per meteor? With 7 meteors per second that makes potentially 2800% Ap (Gangplank has a ratio of 500% if you get hit by all bullets on his ult). With just 100 Ap, you can deal 2800 AoE magic damage per second (Gangplanks ult deals 4625 magic damage over 7 sec with 100 ap).

Overall apart from Ice, her abilities make her very unreliable. Both Fire and Electricity hit randomly. Playing this character would feel like pressing buttons and hoping that you either obliterate the enemy team in an instant or do almost nothing. 10 Stacks on her passive is too high: you will hardly reach that even with max cdr. Her ult is rather boring and doesn't add anything interesting to her kit.

I think you are trying to make up for the power of all these spells by giving them insane mana costs, but I don't think she'll be very fun if a single teamfight has the potential of stripping her of all mana in 5 seconds even if she has 3000 mana. Anivia and Swain use just a fraction of that in the same time.
