Lissandra Ability (LoL): Frozen Tomb

Enemy Cast: Lissandra freezes the target enemy champion, stunning it for 1.5 seconds.

Self Cast: Lissandra encases herself in dark ice for 2.5 seconds, becoming untargetable and invulnerable but unable to take any actions. Lissandra also gets healed for 100 / 150 / 200 (+30% of ability power) (+1% per 1% of missing health) health over the duration.

After casting, dark ice spreads from Lissandra's frozen target after a 0.5-second delay, dealing 150 / 250 / 350 (+75% of ability power) magic damage to enemies. The ice lasts for 3 seconds and slows enemy Movement Speed by 30 / 52.5 / 75%.
