Range of Sight

Posted: December 21, 2008 in Vision

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

    What happens when you place a sentry ward on a cliff?

  2. Phoenix says:

    A sentry ward has 200 AoE vision by “itself” and an 800 AoE “true sight”. If you place a sentry on a cliff, ward’s “itself” vision won’t get blocked by surrounding trees (provided tree is on a lower level than the cliff). Speaking of the “true sight”, it doesn’t get blocked by anything and there’s no ‘extra’ advantage (of true sight) by planting sentry on the cliff.
    So, by planting sentry on cliff you basically gain ‘uninterrupted’ 200 AoE vision around the ward.
    [Basically, planting on cliff is an observer ward strategy to get huge uninterrupted vision]

    Ah, it’s so hard to make sentry wards useful as mini-observer wards.

    This is a late reply but whatever… I actually prefer planting sentries in hidden positions so enemies can’t see it even if they want to… (with gem etc.) maybe behind trees or at any position where they won’t be able to find it. The thing is…
    You buy sentries to counter invisibility but the bad thing is that enemy KNOWS you’ll plant wards! So, to counter them he’ll come up with gem/wards/whatever and try to demolish all your sentries. This will defeat the purpose of your sentries… so better plant them at positions where they cannot see them even with gem (behind trees, obstructions etc.). [and I’ve already stated you earlier that true vision doesn’t get obstructed by anything]
    If you don’t understand what I’m saying, read it again… if still you don’t, tell me and I’ll give you a pic.
