Rylai the Crystal Maiden is a ranged intelligence Hero used as a hard support and disabler. She is perhaps best known for her powerful global mana regeneration aura. This aura allows mana dependent allies to excel during the early to mid game and the laning phase, and allows her to constantly activate her own spells without needing to worry much about the mana costs. She also has a high amount of early game presence with just a few points in her Crystal Nova and Frostbite abilities. Crystal Nova is a powerful area-of-effect nuke that slows both attack and movement speeds of enemies within an area for several seconds, while Frostbite encases an enemy in a block of ice for several seconds, immobilizing it and doing moderate damage per second. Combining these two abilities together along with a laning partner's own spells often results in the quick death of an enemy hero. Although her strong early game presence is quickly lost due to her extreme frailty and poor mobility, she can still inflict a heavy amount of damage in teamfights later on if she is able to channel her deadly ultimate, Freezing Field. Her Arcane Aura, strong disabling and nuking prowess, relative ease of usage, and almost complete lack of item dependence makes her a reliable support caster that can be useful in any team.


Crystal Maiden Rylai, the Crystal Maiden
Play "When Hell freezes over, I'll start calling it Heaven."
Role: Pip roamer.png Support / Pip disabler.png Disabler / Pip ganker.png Nuker / Pip babysitter.png Lane Support
Lore: 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.

  • Despite the visual effects, Frostbite icon.png Frostbite applies its effects immediately and cannot be disjointed.
  • Frostbite icon.png Frostbite deals 50 damage in 0.5 second intervals, starting immediately, resulting in 3/4/5/6 (20 against creeps) damage intervals.
  • Frostbite icon.png Frostbite can deal up to 150/200/250/300 (1000 to creeps) damage (before reductions).

Self Mana Regen Bonus: 2/3/4/5
Cold temperatures promote the essence of magic, causing Rylai's presence to allow spell usage in abundance.


  • Is an aura, so its buff lingers for 0.5 seconds.
  • Stacks with all other sources of flat mana regeneration.
  • The flat mana regen bonus is not considered by percentage mana regeneration increases.
  • Regenerates up to 60/90/120/150 (120/180/240/300 on self) mana in one minute.
  • On level 4, it effectively provides slightly more mana than Arcane Boots icon.png Arcane Boots which is used whenever it's off cooldown (137.5 opposed to 135 in 55 seconds).

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.
  • Every 0.1 second an explosion occurs, for a total of 100 explosions.
  • The spawn location of the ice explosions is not totally random.
    • The radius is basically divided into 4 90° segments (0°-90°, 90°-180°, 180°-270°, 270°-360°).
    • The first explosion occurs within the north-east segment of the radius. The next occurs on the north-west segment, going counterclockwise.
    • Two explosions can never happen in the same segment twice in a row. Every 4th explosion happens in the same segment.
    • Each ice explosion can spawn within a random distance of 195 to 785 away from Crystal Maiden.
  • Can damage units up to 1085 range away (785 spawn radius + 300 explosion radius).
  • The area of effect is centered around Crystal Maiden's current location, not where the spell was cast.
    • This means when her position changes while channeling without getting canceled (e.g. with Force Staff icon.png Force Staff, or an allied Meat Hook icon.png Meat Hook), the affected area will follow her.
  • If each explosion could hit a single target, it would deal up to 10500/17000/25000 (17000/25000/31000) damage (before reductions).
  • Despite the visual effects, the damage is dealt as the falling ice shards are spawned, not upon them reaching the ground.

Recommended items[edit]

Starting Items:

Early Game:

  • Bracer can be upgraded from Gauntlets of Strength to provide a good mix of attributes, the Strength bonus being especially useful to improve her durability.

Core Items:

  • Tranquil Boots allow Crystal Maiden to stay out in the field with increased health regeneration, while offsetting her very low base movement speed and allowing her to roam more effectively.
  • Blink Dagger augments Rylai's mobility, allowing her to position herself for Freezing Field and lock down fleeing heroes with her other abilities.

Luxury Items:

  • Eul's Scepter of Divinity gives Crystal Maiden a second disable and a much-needed increase in movement speed.
  • Ghost Scepter helps against auto-attacking carries by granting Rylai a brief period of invulnerability to physical damage.
  • Scythe of Vyse gives a very reliable disable (Hex) and a powerful mana regeneration boost.
  • Aghanim's Scepter improves Freezing Field's damage output as well as empowering its slow effect.
  • Shiva's Guard gives Crystal Maiden a strong area slow which synergizes with Freezing Field. The armor bonus also makes her much more resistant to physical damage.
  • With Shadow Blade, Crystal Maiden can escape dangerous situations and position herself for fights. It can also be used during Freezing Field, protecting Rylai during the channeling.
  • Black King Bar prevents interruptions to your ultimate channeling as well as increasing Rylai's health pool.



  • Crystal Nova icon.png Crystal Nova is a large area of effect nuke that also slows your enemies. You can hit enemies from 1100 units away with it (700 casting range + 400 radius).
  • Frostbite icon.png Frostbite is a great disable which prevents the target from moving or attacking. It also interrupts channelling spells and teleports. Unfortunately, it does not prevent enemy heroes from casting spells (except for True blinks).
  • Arcane Aura icon.png Arcane Aura benefits the whole team greatly, especially one with a strong caster/ganker line-up, as it grants them a better lane presence due to the increased number of spells they can use.
    • Generally, 3 points in Arcane Aura, with 2 levels taken early, are sufficient for most of the game. Adjust your ability build to the needs of your team.
    • This bonus is doubled on Rylai herself, granting a whopping +5 bonus mana/second at level 4.
  • Freezing Field icon.png Freezing Field is an incredibly strong spell. However, it can be unpredictable and usually gets interrupted by your enemies very quickly. Freezing Field consumes a lot of mana, so use it sparingly.
    • Many players choose not to level Freezing Field until quite late in the game, as it is a situational spell that is most effective in large clashes; and its use consumes a huge amount of mana. However, its slow and gigantic (if unpredictable) damage can be very useful in early game, especially against enemies that lack the means to interrupt it. Let your decision be informed by enemy line-up as well as laning composition.
  • Crystal Maiden's potent spells grant her an incredible early-game roaming and ganking presence, particularly when her slow movement speed is offset with Tranquil Boots.
  • Frostbite's 10 second duration on creeps can be used to earn Crystal Maiden some spending cash in the jungle, either during roams or while her carry's lane is uncontested.
  • Observer Wards and Sentry Wards should be bought over and over again to provide map control throughout the match.
  • Later on, Crystal Nova may be used to help push a lane without contesting carries for last hits, as the damage is not quite enough to kill a wave of creeps. However, make sure to keep it off cooldown in the possibility of an upcoming teamfight.
  • In teamfights, cast Crystal Nova early to reduce incoming damage due to the attack speed slow.
  • If you have a few coins to spare, buy items that boost your survivability, or get yourself an escape/positioning mechanism such as Blink Dagger icon.png Blink Dagger or Force Staff icon.png Force Staff.
  • Freezing Field must be used at the right time to avoid interruption and being focused. Generally speaking, in an encounter it is best used after the initial nuking phase; when the enemy's stuns are on cooldown (building a Black King Bar icon.png Black King Bar will provide immunity to stuns; but Crystal Maiden does not typically get much gold and this can be very difficult to build in a game where your team is not getting a lot of kills). If your team has an initiator with the capability to disable a group of enemies, such as Tidehunter icon.png Tidehunter or Enigma icon.png Enigma, Freezing Field should be used in synchronization with their mass disable. Using Freezing Field very often results in Rylai's death, and she rarely is able to channel it for its full duration, but if she can maintain it even for a few seconds it will be useful for her team.
    • Although Freezing Field's damage can be upgraded with Aghanim's Scepter icon.png Aghanim's Scepter, to do so is to gild the lily; Freezing Field at level 3 is staggeringly powerful even without a scepter and it's wiser to build items that improve her chances of channeling it.
    • When you position yourself for Freezing Field, make sure you do not position yourself within 200 metres of your target as it seems that the explosions happen more frequently at 400 metres away from her. In another words, try stay far enough of everyone will get more damage to her but do not position her too far where her ultimate will not little.


  • Rylai's name in Warcraft DotA was Rylai Crestfall. Her surname was removed in transition to Dota 2 for the implementation of her sibling rivalry with Lina.
  • Crystal Maiden's mana regen aura used to be called Brilliance Aura.
  • In early versions of DotA, Crystal Maiden and Lich Lich used to share the same Frost Nova ability. 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.
  • League of Legends features an item called Rylai's Crystal Scepter, a homage to the Crystal Maiden from the original DotA.
  • Crystal Maiden's leveling-up response Play "Is it cold in here or is it just me?" is a reference to the action movie Demolition Man.
  • Crystal Maiden's respawning line Play "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 Play "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 Play "Can you guess my... favorite poet?" is a reference to Robert Frost due to his last name.
