  • The ability and modifier are not displayed in-game.


  • Essential to victory, Observer Wards allow you to keep watch over areas and spy on your enemies while keeping you and other heroes safe. It is important to keep wards up in key locations, and destroy enemy wards.
  • Observer Wards are considered essential to map control, providing vision for runes, watching out for ganks, and blocking neutral creeps from spawning in the jungle.
  • Although it is common for the support to purchase wards, mid and offlaners can purchase them to set up ganks or block the enemy team's safe lane jungle camp respectively.
  • Avoid placing wards on top of destroyed trees. Trees do not grow back if a unit is obstructing their location, so a ward placed on a destroyed tree prevents it from growing.
    • All destroyed trees re-grow together on a set timer, so if a single tree does not re-grow together with the others indicates that something is blocking it, which could be an enemy ward, or any other invisible enemy.


  • Knowing how to craft a ward is an important skill for artificers of magical goods. Rylai showed great talent at crafting wards, and once considered becoming an artificer.[1]
  • Despite this, the flavor text for this item refers to Observer Wards as plants and states that they are "often cultivated by apprentice wizards." This implies that they are grown as opposed to crafted, directly contradicting the White Sentry's description.
