Not one thrall creature of the depths,
Nor spirit bound in drowning's keep,
Nor Maelrawn the Tentacular,
Shall rest till seas, gem comes to sleep.

  • The True Sight is provided within the whole area, regardless of the carrier's actual vision. It is fully unobstructed.
  • The True Sight is provided by an aura which affects enemies. Its debuff lingers for 0.5 seconds.
  • When the Gem gets dropped on the ground, it continues to provide True Sight around it, for the team that dropped it.
    • This True Sight lasts until the gem gets picked up again.
    • While on the ground, the gem also provides 300 radius flying vision around itself, for the team that dropped it.


  • Gem of True Sight is a risky investment, due to it dropping on death and potentially giving the enemy a free Gem. Therefore, this item should only be bought when having enough survivability and when other True Sight items are not enough.
  • Although often purchased by supports, Gem of True Sight is better carried by more resilient tanks and initiators, who are less likely to die and lose it.
  • In the early game, when heroes are more stationary farming the lanes, Sentries are a far more efficient way to avoid being ganked by invisible heroes.
  • Due to the True Sight being a passive aura, it constantly reveals nearby invisible enemies, making it the most cost effective revealing item, hence the heavy drawback.
  • Gem of True Sight can still sometime be a worthwhile investment when the enemy has no invisible heroes. It is ideal to reliably remove enemy wards over a long term, as the only alternative item to do this are Sentry Wards, but they can be easily wasted if the enemy ward locations are unknown.
  • Gem of True Sight can be dropped to provide flying vision to detect Observer Wards and Sentries on cliffs.


  • Windranger minimap icon.png Windranger ▶️ response while having the Compass of the Rising Gale equipped upon buying Gem of True Sight suggests that the Gem of True Sight is slippery, possibly explaining its nature of dropping upon death.
  • In DOTA: Dragon's Blood. The Gem of True sight is used as a bargaining tool for Mirana, Invoker and Terrorblade.
