Naga Siren

Slithice, the Naga Siren is a melee agility Hero that can cause huge damage with her illusions, while also having useful disable abilities. Slithice is an item dependent hero, usually built as a carry. With the right style and inventory choices she can overpower many other heroes that deal strong physical damage, while having a Diffusal Blade helps her to handle the magical power of the enemy. 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. Her ultimate has multiple uses, such as saving her and/or her team from being killed, stopping enemies that are running away, ruining a gank, or just disabling strong foes that she can't defeat alone.

Tips

 * 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 many movement spells such as Anti-Mage's Blink.
 * 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 melts creep waves, Mirror Image outputs tremendous damage to towers, and Song of the Siren makes it very difficult for the enemy team to gank her even if overextended.
 * Rip Tide will affect targets around Siren's Mirror Images and other illusions. You can send them into enemy territory to nuke far-off targets, due to their expendable nature.
