Crystal Maiden is a ranged character. His primary attribute is intelligence. The hero is mainly taken to the easy lane as a support. Most effective in the early and mid game.
A very useful ally in the early game due to the Arcane Aura ability, which allows allies to use their spells more often. Crystal Nova slows all enemies in the area of application, making them more vulnerable for Crystal Maiden’s allies. Frostbite allows the hero to attack a single target, and also helps to farm large camp creeps, which greatly speeds up the purchase of desired items. Her most important ability in a team fight is Freezing Field, which is a formidable weapon for the opponents due to its long range and high damage. Buying Aghanim's Shard upgrades this ability, allowing Crystal Maiden to move around the battlefield, and with Aghanim's Scepter, the spell will limit the movement of the affected enemies.
Raised with her fiery older sister Lina, Rylai the Crystal Maiden soon found that her innate elemental affinity to ice created trouble for all those around her. When she found herself banished to the cold northern realm of Icewrack, her mastery of the Frozen Arts deepened, and now her skills are unmatched.
