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 and with the right style and inventory choices she can overpower many other heroes that deal strong physical damage while casting her all four active skills 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 magic 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 skill for team battles, the 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. Slithice is a mighty single target huntress and a great team fighter, using her powerful water magic, skills in combat, and her enchanting voice.

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 Magic 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 Necrolyte'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 skill 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 skills 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 skill to impede your pursuers. Any opposing target who approaches you will be stopped in their tracks, making for a smoother exit.
 * 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.

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 hands.
 * "Slith" in latin is used to describe a quick escape, while "Slithice" means a cruel escape.
