Melee Attack Range Bonus: 150
Ally Deny Health Threshold: 50

  • The ability and modifier are not displayed in-game.
  • Melee Melee units have an extra 150 attack range when attacking Observer Wards.
  • Observer Wards can always be attacked by their owner, and can only be attacked by other ally heroes if they are within the spawn areas of neutral creeps, regardless of the ward's current health.
    • Observer Wards receive 10 damage from ally heroes when it has over 50 health.


  • 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.
