Naga Siren/Counters

Bad against...

 * Both of Lion's and  destroys Naga Siren's illusions in an instant. Making it hard to teamfight or push against a team with Lion.
 * is an AoE disable with good damage. If used well, it can help distinguish the true Naga by the damage they take (illusions take more damage).


 * Outworld Devourer's deal bonus damage to illusions which is a very good way dealing with Naga Siren's illusions.
 * will likely instantly kill all illusions.


 * Huskar's ultimate ability does almost one-hit kill a Naga Siren illusion because of the percentage based damage. This makes it very hard to push against a Huskar.


 * Zeus' abilities deal high amount of burst magical damage which ignores Naga Siren's high armor. Zeus' is also a good way to destroy pushed in waves and clumped up Naga Siren illusions.


 * Timbersaw's innate tankiness is very hard to deal with as Naga Siren. Timbersaw's high Pure Damage and spammable AoE nukes can also destroy Naga Siren's illusions very fast.


 * will destroy her illusions and proc more often due to being hit by more attacks.


 * Despite the fact that Enchantress is a single-target hero due to her reliance to creeps, Naga Siren will have hard time killing Enchantress because of.
 * Naga Siren will need help from Nuker to take her down.

Others

 * has many tools to deal with a crowd of Heroes, which will work well against a crowd of illusions.
 * can just mess up with entirely: His  is AoE, which can bind her illusions, his  is a powerful AoE nuke and will vanish her illusions and he is 2/3/4 s, not only one, so her  will not work efficiently against him.
 * Cleave Heroes will vanish her illusions. Such includes:, , (via item),  (via item), etc.
 * So will Heroes with AoE nukes.

Items

 * prevents most of her spells, in special her ultimate.
 * can be used when you are rooted by her, returning all the damage she and illusions deal to you while you're disabled.
 * A substitute for might be, preventing you taking damage from her attacks and her illusions attacks (altought you will still take damage from her.
 * huge AoE damage (depending on the Hero) will kill her illusions quickly.

Good against...

 * Song of the Siren will waste.
 * Ensnare fully works on ed targets.
 * However, is dispellabe with any dispel, and so can be dispelled by.
 * As an agility hero that relies on illusions, Naga is one of the most natural carriers, the bane of Omniknight.
 * As for 7.00, is not dispellable, but  is.


 * Naga Siren is a natural split-pusher. With a radiance equipped, she will easily out-push Furion, farming his treants in the process.
 * Ensnare prevents . Even if he hid inside, Song of the Siren lasts long enough to alleviate this hindrance.


 * Song of the Siren lasts long enough to prevent a successful (but only if Naga wasn't the target).


 * Ensnare disables Lanaya's invisibility and Blink Dagger (Core Item on TA), and your illusions will break her easily.


 * Ensnare and Song of the Siren cancel Crystal Maiden's ultimate. Her raw movement speed also allows her to catch up with CM for a quick kill.


 * Naga Siren can make landing of Chen's combo very hard due to being an illusion hero.
 * will prevent activating, despite not silencing him.

Others

 * as a single target dealer, will not fare well against . He might as well try to her, but her  will dispel the effect. Also,  reveals invisible units while they're rooted, putting The Hunter in a tricky situation (not to mention that this is his only escaping ability).
 * is a carrier built entirely with auto-attacks, having 0 AoE presence and no spell power. Due to this, he can't deal with illusions or Naga's.
 * would follow the same weaknesses as the : squish, single target dealer, invisibility as his only escape and no way to counter her illusions. However, depending on the players builds and playstyles, The Bone Fletcher can be superior to her, or vice-versa (positioning, sucessful ganks, dispellable items, silencing items, etc.).
 * E.g.: is a common item on, and it can be used to silence her and burst her down, preventing her from casting anything that would save her. However, if she builds a  she might dispel the silence and turn against him, whereas he can build a  and his damage might be enough to tear down her illusions, and so goes on.

Works well with...

 * In the early game, you can deal huge amounts of physical damage with if you surround an enemy with your s. This can be setup with  and the damage can be further amplified through armor reduction with.
 * The combination of and  should result in some daring/clutch escapes for you and your allies.
 * Worse for worse, you can always use your song as a means to buy time for to tick into effect, forcing a fight with an armor difference to your advantage.


 * Disruptor's and  can both be cast pre-emptively during Song of the Siren, dooming your enemies before the song ends.
 * There is almost nothing the enemy team can do if they are trapped into both spells and Disruptor also purchased an.


 * will help Razor to fully steal an enemy's damage (preferably their carry in the middle of a fight) with.


 * works very well as a follow up Song of the Siren for perfect teamfights in the early game.
 * In later stages, odds are they will have either a to dodge the Ravage or a  to negate it, wasting your perfect 5-man Sleep.


 * Like Tidehunter, you can use as a follow-up to the Song in the early game.
 * You can also use Ensnare as a set-up for.

Others

 * Any hero that has a good follow-up to your Song:, , ...
 * A special mention goes to as zombies from his  will keep spawning during the Song.
