Innate: Upon taking fatal damage, Anivia transforms into an egg, dispels all debuffs, with 100% of her maximum health for 6 seconds, during which she cannot act. While in her egg form, Anivia gains -40 / -25 / -10 / 5 / 20bonus armor and bonus magic resistance. If the egg survives, Anivia is reborn with its current health.
Triggering Rebirth while affected by a channeled ability like Drain or Nether Grasp will not end the channel early and the egg will still take damage.

100 / 150 / 200 / 250 / 300 (+ 100% AP)
The damage of Frostbite is calculated on-hit. If the target is no longer marked as recently stunned by Flash Frost or damaged by a fully formed Glacial Storm while Frostbite is in the air, it will deal standard damage.
Frostbite's double damage on a target is listed as a critical strike both in-game (damage text) and in post-game screen ('Largest Critical Strike') but it cannot actually critically strike nor will it scale with Infinity Edge's modifier.
Frostbite has a different sound effect when it hits a target for double damage.
Active:Anivia calls forth a driving rain of ice and hail at the target location, dealing magic damage each second to enemies within, slowing them for 1 second.

Empowered damage per second:
120 / 180 / 240 (+ 37.5% AP)
