Dota 2/Rylai the Crystal Maiden

Crystal Maiden is a ranged intelligence hero that is almost always played as a dedicated support. She has a very helpful aura that covers the entire map, giving her allies mana regeneration. She is also a great disabler with her Crystal Nova and Frostbite. Her ultimate, Freezing Field, can hinder any hero's escape as her teammates catch up. Crystal Maiden, being a support intelligence hero, is very frail. Get caught out of position, and she will go down within seconds.
