Idea for new Lissandra passive

This is a very, very rough idea. The numbers are in no way good, but thats why I'm putting it here. These are just two very general ideas for a new passive for Lissandra that I though might be nice. Here goes:

Ice Infusion Whenever lissandra hits an enemy with an ability that is has been CC'd by her, the ice melds together and gives lissandra power gaining mana equal to 150% the cost of the ability, health equal to 20% or the damage dealt, an armor and magic resist equal to 5% of the damage dealt (lasts for 10 seconds) This effect can only trigger once every 15 seconds.

(Insert ice based name here) Lissandra's Q and Ult (enemy cast) apply the "Frosted" debuff to enemy champions for 3 seconds. Lissandra's basic abilities will detonate the debuff to give the ability additional effects. After detonation effect can only be triggered after a 6 second cooldown.

Q: Provides Lissandra with 5% of her maximum mana, and refreshes the debuff no matter the cooldown.

W: Lissandra gains an HP shield equal to 200% of the damage dealt for 3 seconds. Or Lissandra regenerates 75/90/125/140/150 health over 5 seconds and gains 10/15/20/27/35 armor and magic resist for 5 seconds.

E: Lissandra gains another charge of her E that she can use for 1 second before I toes back on cooldown.
