Range Of Sight - DotA-Allstars Guide

While playing DotA, many of you must have cursed yourself for letting that enemy escape with 10hp. Why? Just because that hero got out of your sight. What is this sight actually? The term Range of Sight, or Sight Range, is used to describe how far a hero will see on day/night without taking the terrain modifications into account. Allied units share vision around the map. You share sight with allied creeps, buildings/towers, heroes, summons, and illusions. Use the following information to organize team battles.

Hero Sight Range

The Sight Range of most of the heroes is 1800(day) / 800(night). There are some exceptions:

Aiushtha, Enchantress: 1800 / 1200

Rooftrellen, Treant Protector: 1800 / 1200

Gondar, Bounty Hunter: 1800 / 1000

Traxex, Drow Ranger: 1800 / 1700

Mirana Nightshade, Priestess of the Moon: 1800 / 1200

Puck, Faerie Dragon: 1800 / 1200

Leshrac the Malicious, Tormented Soul: 1800 / 900

Balanar, Night Stalker: 1200 / 1800. So you now know that balanar can see you at night even when you can't.

Meepo, Geomancer: 1800 / 1800. Ganking a nice meepo is never easy.

Alleria, Windrunner: 1800 / 1200
