Naga Siren

naga siren dota 2

For the race in Dota 2 lore, see Naga.

Slithice, the Naga Siren, is a melee agility hero who can be played both as a late-game carry and an early/mid-game support. Slithice is an item dependent hero yet with the right style and inventory choices she can overpower many other heroes that deal strong physical damage while casting her active abilities to handle her enemies altogether and turn the tides. Mirror Image creates three illusions to wreak havoc upon her enemies. Ensnare is a very useful spell with several unique features. It not only holds an enemy in place, but also prevents them from blinking and going invisible. Rip Tide calls the forces of the seas, allowing the Siren and her illusions to unleash a wave of magical water to wash away foes and degrade their armor. The Song of the Siren is the ultimate ability for team battles; Naga Siren performs a mystical song to put her enemies to sleep in an area around her. Song of the Siren is her tool for initiation, as while her enemies are under her slumber her allies can come forth and prepare to unleash their attacks after the song wears off. Time is Naga’s best friend, for as the game wears on, Slithice will gradually consume more and more of the map and engulf enemy towers and heroes like the rising tide itself.



Slithice, the Naga Siren

▶️ “I sing the Siren song of war.”

Among the high-sworn of the Slithereen Guard there is a solemn vow oft repeated before battle: No Slithereen may fail. In truth, these words are equal parts oath and enforceable covenant, for those who fall short of their duty are banished from the order. To fail is to be other than Slithereen.

Once most highly esteemed of her race, Slithice for many years commanded a battalion of her fellows, using her formidable voice as her greatest weapon. Powerful, sinuous, serpentine, she led her deadly Guard in defense of the Deep Ones, and the great wealth of the sunken cities. But in the final battle of Crey, her forces were driven back by a marauding army of levianths intent on finding tribute for their god Maelrawn. After the long and bloody onslaught, as the bodies were cleared from the sunken halls, a single jeweled chalice was found missing from the trove. Of her hundred Guard, only a handful survived, but their bravery and sacrifice were of little consequence. What mattered was that treasure was taken. Honor destroyed. And so Naga Siren was cast out. Banished to search for the stolen chalice. Though she might add a hundred times her weight to the golden trove, she is doomed to live apart until that day she returns that which was taken. For no amount of gold is equal in honor to the honor she lost.

Recommended Items[]

Starting items:

Early game:

Mid game:

Late game:

  • Octarine Core reduces the cooldowns of Naga Siren’s abilities, greatly improving her pushing power and making her much harder to gank. The Spell Lifesteal has little effect on her own abilities, but can be combined with Radiance to let her illusions shrug off damage from creeps.

Situational items:

  • Quelling Blade grants bonus damage against creeps to secure last hits.
  • Infused Raindrops gives good mana regeneration to keep using your abilities, and allows Naga Siren to survive some magical burst.
  • Magic Wand provides attributes and burst of health and mana, a useful sustain item no matter the role of Naga Siren.
  • Arcane Boots solve Naga Siren’s early mana issues, and you can later disassemble it to recycle the Energy Booster into Octarine Core.
  • Drum of Endurance gives solid overall attributes, and an active that increases movement and attack speed to Naga Siren, allied heroes, and illusions around her.
  • Meteor Hammer‘s area stun combos well with Song of the Siren, giving the enemies little time to react.
  • Spirit Vessel grants Naga Siren various bonuses like health and movement speed, as well as an ability to heal teammates or counter enemy healing.
  • Blink Dagger grants mobility so Naga Siren can better initiate with Song of the Siren.
  • Boots of Travel makes Naga Siren an incredibly strong pusher and increases her farm speed.
  • Radiance gives a lot of damage and the Radiance aura works on illusions, giving Naga Siren the ability to farm multiple areas of the map at the same time thanks to Mirror Image. Makes ultimate ability very dangerous. Positioning deep inside of enemies prevents enemies from blinking away or in once ultimate expired and they got a tick of damage from Radiance.
  • Heart of Tarrasque provides a large amount of health, tanking Naga Siren and her illusions up massively. It also provides enormous passive health regeneration while not fighting, so she can return to fights faster with full health.
  • Butterfly offers bonus attack speed, damage, and armor, as well as evasion that gives more survivability to her and her illusions.
  • Linken’s Sphere provides good all around attributes as well as regeneration, which allows Naga Siren to stay farming without having to go back to base. On top of that, it provides a spellblock which can make Naga Siren harder to kill in conjunction with Song of the Siren.
  • Aghanim’s Shard provides great heal to allied heroes during Song of the Siren, a terrific support item to boost team’s survivability and turn around teamfights.






  • The DotA Naga Siren from Warcraft universe sports the same weapons as Slithice, the only difference being that the DotA version had one weapon, and four arms, while the Dota 2 has two weapons and two arms.
  • Song of the Siren’s ▶️ sound is based on this ▶️ voice line of Naga Siren. Whether there is an extended version of that line or if the rest of the song was manually put together is unknown.
