How to counter Crystal Maiden

In lane

Juggernaut
• Blade Fury makes Juggernaut ignore all of her spells. Combined with her low movement speed, she is very likely to die to this spell. • Her low movement speed and slow attack animation make Healing Ward hard to kill. • Freezing Field no longer gives her bonus armor, meaning she can just die to Omnislash while trying to use it.
Rubick
• All of her spells are a good steal, especially Freezing Field and Frostbite. • He can cancel Freezing Field with Telekinesis and then cast it himself after stealing it with Spell Steal.
Lifestealer
• Same as with Juggernaut, Rage makes him not care about her spells and just kills her.

Pipe of Insight
• If you are struggling with interrupting Freezing Field or killing her during it, this is a good item to soak some of the damage. • All of her damage is magical.
