How To Make Anivia Viable

Crystallize Anivia summons an impassable wall of ice 400/500/600/700/800 units wide, blocking all movement. The wall lasts for 5 seconds before it melts.

New: Enemy units attacking through the wall have their attack speed reduce by 15%.

New: When an Enemy unit passes through the wall of ice(i.e. Dash, Knockback), they take 40/70/100/130/160 (+50% Ability Power) magic damage and are slowed 10%/15%/20%/25%/30% (+5% Ability Power) for 1.1/1.2/1.3/1.4/1.5 seconds.

This punishes high mobility champions while maintaining Anivia's balance.
