  • 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 off-laners can purchase them to set up ganks or block the enemy team's safe lane jungle camp respectively.


  • 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]
