Naga Siren

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 all four 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 a place, but also prevents them from blinking and going invisible. Even if the enemy is spell immune, Ensnare can still target the enemy unit. 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.

Tips

 * Rip Tide's damage and armor reduction means that Naga Siren can hit hard even in the early game, and is more than viable to level first. Even when fully leveled, its instant damage is very low, however. Its most important attribute is ultimately armor reduction, which can multiply the physical damage that is dealt.
 * Rip Tide will affect targets around Naga's Mirror Images and other illusions. Illusions can be used to engage for Naga, due to their expendable nature.
 * It is important to keep Ensnare's unique properties in mind. Its major downside is that Ensnare only prevents movement, and does not stop enemies from fighting back with attacks and spells.
 * Ensnare can be applied to targets with Spell Immunity, most notably holders of Black King Bar.
 * Ensnare will interrupt channeling abilities such as Witch Doctor's Death Ward.
 * Heroes with invisibility such as Bounty Hunter and Weaver should be prime targets of Ensnare, as they will be revealed for its duration.
 * Ensnare will also prevent the usage of teleportation such as Anti-Mage's Blink.
 * Ensnare can also be used to snare the Animal Courier, preventing it from moving allowing for an easy kill.
 * Mirror Image's period of invulnerability is very short, but can allow Naga Siren to dodge many spells. Some easier examples (due to slow projectile speed) include Sven's Storm Hammer and Necrophos's Death Pulse.
 * Naga Siren can push with impunity; Rip Tide can affect entire creep waves, Mirror Image's illusions can deal tremendous damage to towers, and Song of the Siren makes it very difficult for the enemy team to gank her even if overextended.
 * Song of the Siren is often used to make another initiator's job much easier, as it gives them time to position themselves while your targets are stunned.
 * It is possible for you to rudely interrupt your teammates' momentum when using this ability for your own sake. Avoid using it as an extra team-fight disable when your teammates already have the upper hand disabling the enemy, as it wastes their abilities by completely making their targets invulnerable. Opt for using Ensnare as a disable instead.
 * When a crucial escape is necessary (i.e. when losing a team fight), use this ability to impede your pursuers. Any opposing target who approaches you will be stopped in their tracks, making for a smoother exit.
 * In a bad situation, You can use a Town Portal Scroll during Song of the Siren, or you walk away for a smooth escape.
 * The interaction between Song of the Siren and an opposing Black King Bar is important. BKB can help enemies avoid being locked down by Song, but it may also make that enemy vulnerable in a teamfight by allowing Naga's team to focus on one target without backup, especially when combined with Ensnare. Enemies should try to activate their BKBs together or take special care in their positioning to reduce this danger.
 * A very strong combination on Naga Siren is Linken's Sphere and Boots of Travel. This makes Naga an incredibly versatile pusher, and Linkens makes it nigh impossible to catch her off-guard while pushing, allowing for an easy Song of Siren escape. Another item worth mentioning is Radiance. Slithice's illusions carry the Radiance aura, allowing farming over large areas and greater combat presence.
 * Note that none of the auras from Vladmir's Offering will affect illusions from Mirror Image.
 * Although not mentioned and highly irregular, an Octarine Core may be considered in the latest stages of the game as the 25% cooldown reduction is very handy considering how long the cooldowns of her spells are normally. The life steal effect also works with the burn damage from Radiance if equipped.

Trivia

 * 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.
 * The levianths in Slithice's lore worship the god Maelrawn, the same god worships.  Though it is likely that his species is levianth, it's unlikely he was part of the raid in Slithice's lore given Tidehunter's independent lifestyle suggested in his own lore.
 * Song of the Siren's Song of the Siren.mp3 sound is based on this naga sing 01.mp3 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.
