Stop Freezing Field

Rylai, the Crystal Maiden, is a ranged intelligence hero who uses the power of frost and ice to disable and dispatch her foes. A slow and fragile support, Crystal Maiden's strength lies in her battery of strong nukes, disables and slows. Crystal Nova is an area-of-effect nuke that slows enemies' attack and movement speeds, while Frostbite immobilizes an enemy in a block of ice, dealing moderate damage per second. Coordinating these spells with a laning partner's own abilities will bring many an enemy to their knees. Her passive Arcane Aura also improves the mana regeneration for heroes in Rylai's team, multiplying their spellcasting in the early game. Later on, she has the potential to lay waste to her enemies in teamfights if she can channel her deadly ultimate Freezing Field uninterrupted. Her global mana aura, strong disables and nukes, and a lack of item dependence make Crystal Maiden a reliable and, with judicious use of her ultimate, a devastating support caster.


Crystal Maiden minimap icon.pngRylai, the Crystal Maiden
▶️ "When Hell freezes over, I'll start calling it Heaven."
Born in a temperate realm, 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. Wellsprings and mountain rivers froze in moments if she stopped to rest nearby; ripening crops were bitten by frost, and fruiting orchards turned to mazes of ice and came crashing down, spoiled. When their exasperated parents packed Lina off to the equator, Rylai found herself banished to the cold northern realm of Icewrack, where she was taken in by an Ice Wizard who had carved himself a hermitage at the crown of the Blueheart Glacier. After long study, the wizard pronounced her ready for solitary practice and left her to take his place, descending into the glacier to hibernate for a thousand years. Her mastery of the Frozen Arts has only deepened since that time, and now her skills are unmatched.

Ability Draft Notes
Ability Draft Notes:
Upgradable by Aghanim's Scepter.
Frostbite must be drafted as well for it to get applied.
Once the place of her exile, Icewrack has become an anchor for Rylai's frigid onslaught.


  • The slow is applied to all enemies within the radius in 0.1-second intervals, regardless of the ice explosions.
  • The explosions occur in 0.1 (Talent 0.0833) second intervals, starting 0.1 (Talent 0.0833) seconds after cast, resulting in 99 (Talent 121) explosions.
  • Each ice explosion can spawn within a random distance of 195 to 785 away from Crystal Maiden.
    • The explosion spawn radius is divided into four 90° segments (0°–90°, 90°–180°, 180°–270°, 270°–360°).
    • The first explosion occurs within the north-east segment of the circle, following explosions proceed counterclockwise.
  • With the max spawn radius and explosion radius, it can damage units up to 1085 range away.
  • The average damage is roughly constant up to a radius of 485, falling off after that.
    • It is slightly less than 50% at a radius of 785. The very center does 5% more damage.
    • Deals about 2000/3300/4800 (Upgradable by Aghanim's Shard. 2400/3960/5760) damage to enemies within 485 range over the full duration, ±1.9 (Upgradable by Aghanim's Shard. ±2.28) explosions.
  • The radius is always centered on Crystal Maiden and follows her even when she is moved.
  • Despite the visual effects, the damage is dealt as the falling ice shards are spawned, not upon them reaching the ground.
  • With Aghanim's Scepter icon.png Aghanim's Scepter, Freezing Field provides an aura which tracks enemies within the area. The tracker lingers for 0.1 seconds.
    • If an enemy unit is affected by the tracker for 1.75 seconds, Frostbite is applied to the enemy unit based on its current level.
    • A unit can only be frostbitten once per cast of Freezing Field. Even if they re-enter the area, they are not affected a second time.
    • If a unit is already frostbitten by a manual cast, it can still be frostbitten again by Freezing Field, refreshing the duration.
    • The tracker resets whenever it is reapplied to a unit. This means a unit must be affected by it for 1.75 seconds continuously in order to be frostbitten.
    • The tracker is placed on enemies even without having Aghanim's Scepter, tracking the duration enemies spend within the area normally.
    • This means if Freezing Field is upgraded while channeling, enemies which have been in the area for more than 1.75 seconds instantly have Frostbite applied to them.
    • The tracker does not affect invulnerable or hidden units.
  • With Aghanim's Shard icon.png Aghanim's Shard, Freezing Field no longer requires to be channeled, so that Crystal Maiden can act freely during it.
    • However, her movement speed is heavily slowed. This is a regular slow and can be off-set by movement speed bonuses, including haste.
    • Freezing Field is interrupted if Crystal Maiden gets stunned, silenced, cycloned, feared, hexed or slept during it.
    • It also stops when Crystal Maiden dies, or when she uses the Stop Freezing Field sub-ability.

Recommended Items[]

Starting items:

  • Tango icon.png Tango provides Crystal Maiden with health regeneration to stay in lane and support her teammates without being harassed away and being forced to return to base
  • Healing Salve icon.png Healing Salve also restores health to Crystal Maiden or her allies.
  • Clarity icon.png Clarity is a useful purchase due to Crystal Maiden's low base intelligence preventing her from casting too many spells in the laning stage.
  • Enchanted Mango icon.png Enchanted Mango can allow her to bring both of her disables to bear on an enemy, greatly increasing the odds of a kill during a gank.

Early game:

  • Magic Stick icon.png Magic Stick is very useful on Crystal Maiden to sustain enemies' spammable abilities during laning stage.
  • Boots of Speed icon.png Boots of Speed are a crucial early purchase on Crystal Maiden due to her extremely low base movement speed. Increasing her mobility allows Crystal Maiden to get within range to cast her disables on her foes, or outrun pursuing enemies.
  • Wind Lace icon.png Wind Lace also gives movement speed boost for cheap, and builds into various items.

Mid game:

  • Tranquil Boots (Active) icon.png Tranquil Boots are the cheapest upgradable boots available and allow Crystal Maiden to remain out in the field for extended periods of time. As Arcane Aura restores her mana pool while Tranquil Boots's passive heals her, Crystal Maiden can stay out in the field indefinitely and never need to return to base. The increased movement speed is also a boon, allowing her to roam, gank, and flee more effectively.
  • Magic Wand icon.png Magic Wand is a cheap source of extra attributes, which Crystal Maiden lacks. The increased charge storage also allows her to do more in fights.
  • Glimmer Cape icon.png Glimmer Cape can be a useful item to purchase if you intend on making use of Freezing Field regularly. Casting the active on yourself prior to jumping in with your ultimate can give you a little extra time to channel it. In other situations, it can be an awesome stealth initiation, escape, or survivability tool when used either on Crystal Maiden or her ally.
  • Blink Dagger icon.png Blink Dagger augments Crystal Maiden's mobility, allowing her to instantly jump within range for locking down enemy heroes with her disables. It allows her to move around the map more easily either to support her teammates or to escape pursuing enemies.

Late game:

  • Eul's Scepter of Divinity icon.png Eul's Scepter of Divinity grants Crystal Maiden additional movement speed, a larger mana pool, and mana regeneration. It is generally built if an additional disable against enemies is needed.
  • Force Staff icon.png Force Staff provides Crystal Maiden with repositioning abilities and increases the size of her mana pool to allow her to cast her disables more easily. Particularly, it is a good choice if saving up for a Blink Dagger is unfeasible.
  • Black King Bar icon.png Black King Bar is an expensive luxury item that should be considered only if given farm priority and all other support duties have been met. It prevents interruptions to Crystal Maiden's ultimate as well as increasing the size of her health pool.

Situational items:

  • Ghost Scepter icon.png Ghost Scepter gives survivability against attacking carries by granting Crystal Maiden a brief period of invulnerability to physical damage as well as some additional attributes. The active is also useful for preventing enemies from ending the channelling of Freezing Field by attacking her.
  • Urn of Shadows icon.png Urn of Shadows is a good utility item for a roaming Crystal Maiden, as it can add a little periodical damage to her nukes or be used to recover health after ganks. The additional attributes and armor tank her up a bit, while the mana regeneration works alongside Arcane Aura to keep her mana topped up.
  • Drum of Endurance icon.png Drum of Endurance gives Crystal Maiden attributes to tank up. The extra movement speed allows her to position for casting spells.
  • Veil of Discord icon.png Veil of Discord is a cheap utility item that gives Crystal Maiden an attribute boost. Besides the attributes, the spell damage amplification allows her team to do more damage in fights with abilities, especially Freezing Field.
  • Aether Lens icon.png Aether Lens is a strong caster item that greatly improves Crystal Maiden's disabling capabilities. The item facilitates casting spells from her small mana pool. The increased cast range allows Crystal Maiden to cast Frostbite and Crystal Nova from longer ranges to catch enemies.
  • Meteor Hammer icon.png Meteor Hammer can be used as an extra means of disabling enemies when combined with Frostbite. It provides Crystal Maiden with useful attribute and regeneration bonuses and improves her team's pushing potential.
  • Aghanim's Scepter icon.png Aghanim's Scepter can give Crystal Maiden a large amount of lockdown ability with Freezing Field as well as give her attributes across the board, particularly her health and mana pool, giving her both extra survivability to cast the ultimate and the mana to do so at higher levels. If your team can prevent Freezing Field from being interrupted, it can be a strong luxury item to invest in once you have the mobility to deploy it reliably.
  • Scythe of Vyse icon.png Scythe of Vyse is a very expensive support item, however, it gives a very reliable ranged hard-disable, a larger mana pool, some more HP, and a powerful mana regeneration boost.
  • Shiva's Guard icon.png Shiva's Guard gives Crystal Maiden a strong area slow which synergizes with Crystal Nova and Freezing Field. The armor bonus also makes her much more resistant to physical damage, making it harder to focus her down.

Complexity: ★☆☆
Playstyle: Wherever Rylai went, the cold went with her. Fields and orchards withered in her wake, leaving her parents no choice but to pack her off to Icewrack, a realm in the frigid north. Under the tutelage of a hermit wizard, Rylai learned to imprison her enemies with Frostbite, holding them in place as she freezes the ground with Crystal Nova. Magic flourishes under her Arcane Aura, stimulating mana regeneration in all her companions. In the heat of battle, Rylai keeps a cool head. Channeling her elemental talents, the Crystal Maiden summons enormous shards of ice from the skies, obliterating all foes foolish enough to remain in her Freezing Field.





  • Rylai is one of the oldest heroes from the original DotA in Reign of Chaos DotA. Her title used to be Frost Maiden.
  • Rylai's name in Warcraft DotA was Rylai Crestfall. Her surname was removed in the transition to Dota 2 for the implementation of her sibling rivalry with Lina.
  • Crystal Maiden's Arcane Aura used to be named Brilliance Aura.
  • In early versions of DotA, Crystal Maiden and Lich minimap icon.png Lich used to share the same Frost Blast ability (although they were both named Frost Nova). However, in later updates, Crystal Maiden's Frost Nova was changed to Crystal Nova, turning it into a free-cast area-of-effect ability, while Lich kept the original effects.
  • In Warcraft DotA, Crystal Maiden's Frostbite can freeze the enemy's Fountain and the duration was counted as creep.
  • League of Legends features an item called Rylai's Crystal Scepter as an homage to Crystal Maiden, boosting Ability (spell) Power and adding a slowing effect to spells and abilities.
  • In World of Warcraft an Alliance NPC is named Rylai Crestfall, a homage to the original Crystal Maiden from Warcraft III's DotA.
  • Crystal Maiden's leveling-up response ▶️ "Is it cold in here or is it just me?" is a reference to the action movie Demolition Man.[1]
  • Crystal Maiden's respawning line ▶️ "You only live ice..." is a reference to the 1967 James Bond film You Only Live Twice based on the novel of the same name.
  • Crystal Maiden's line ▶️ "It's all fun and games until someone's frozen solid." is a reference to a novel written by Christopher Brookmyre entitled All Fun and Games until Somebody Loses an Eye.
  • Crystal Maiden's rare response ▶️ "Can you guess my... favorite poet?" is a reference to Robert Frost due to his last name, and also an allusion to Frost's poem "Fire and Ice". Crystal Maiden is the ice, and her sister Lina is fire. An excerpt: "Some say the world will end in fire, some say in ice ... know enough of hate, to say that for destruction ice is also great, and would suffice.
