Naga Siren

Mirror Image applies basic dispel on cast.

Mirror Images can be used to deny runes or to deceive the opponents about your hero's presence.

Make sure pull camps are unblocked as the lane will be pushing frequently due to Rip Tide. Ask your support to start with a sentry.

Setup hotkeys to easily split up your illusions.

Use Mirror Images non stop to have an upper hand when it comes to lasthitting.

Consider putting a point in Ensnare around level 4 but only if you can get a kill out of it.

Naga is not a particularly good laning hero. Get as many levels as you can and move to the jungle.

Keep sidelines pushed out by illusions and farm opponents' camps more and more as you get stronger.

Be quick at judging the situation and pop Song of Siren when it starts going downhill.

You can use Song of the Siren to secure Roshan kill.

Aghanim's Scepter is a great pick up to control spell-immune heroes.

Kill Mirror Images to cripple Naga's last hitting capabilities on the lane.

Hex, Drains and Dagon destroy Mirror Images instantly.

Naga Siren farms quickly with Mirror Images. Smoke on her, place deep wards and block camps with sentries.

Items that provide AoE damage, especially magical damage, are great at dealing with Mirror Images.

Crimson Guard and armor items are great against Naga's physical damage.

Naga is great at split-pushing and ratting. Consider getting Boots of Travel on a Core.

Naga can pop Song of the Siren and finish Roshan. Be mindful about it when taking or contesting Roshan.
