Naga Siren is a melee character. Her primary attribute is agility. The hero is mainly taken to the easy lane as a carry. Most effective in the late game.
The Naga Siren has a big farming potential and is also effective in demolition and team fights thanks to her Mirror Image and Rip Tide abilities, which allow her to deal a lot of physical damage. Even the fastest opponent will not get away from Naga Siren when she uses Ensnare. She can also survive in almost any situation thanks to Song of the Siren. Being upgraded with Aghanim's Shard, this ability allows the hero to heal nearby allies. Aghanim's Scepter buffs Ensnare and makes it almost impossible for an enemy to escape from Naga Siren.
Once most highly esteemed of her race, Slithice for many years commanded a battalion of her fellows, using her formidable voice as her greatest weapon. After the long and bloody onslaught, a single jeweled chalice was found missing from the trove. Of her hundred Guard, only a handful survived, but their bravery and sacrifice were of little consequence. And so Naga Siren was cast out. Banished to search for the stolen chalice.
