Crystal Maiden 25lvl right talent: Frostbite roots through spell immunity

[Philosoph228]

As the enemies gather 5 BKBs, this renders out Crystal Maiden as an useless hero in late game. There no control nor damage through spell immunity.
It would be great if there was a such upgrade for CM to able to, at least, control enemy heroes in BKB, even without causing magical damage from her spells.

Wait out the bkbs and jump in. Ive had cm carry a game like that. Everyone dive bkbs pop off. some kiting. Bkb runs out enemy gets a kill your team gets a kill then cm comes in ults and gets 4 kills. Its fine as it is just play strategically instead of brute forcing it with 25 talents lol.
