Observer Ward

Observer Ward is an Item purchasable at the Main Shop, under Consumables. It produces an invisible Observer Ward to spy on an area, but does not have True Sight.

Absolutely 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 deny enemy wards.

Additional Information
Observer Wards, despite not detecting invisible enemies, provide a large sight range of 1600 AoE around them and last for 6 minutes after being placed. They are absolutely essential to map control. Wards are one of the few items in the shop that have a limited stock, and rightfully so. They can be used to provide vision for Runes, watch out for Ganks, and to block neutral creeps from spawning in the Jungle.

It is crucial to place and continue to place wards. Knowing where your enemies are and what they're doing will keep you prepared on on your toes for surprise attacks, and the added vision can come in handy at night.

Because of their usefulness, Observer Wards have a maximum stock of 2 in the store. The stock takes 6 minutes to replenish, but each stack contains 2 wards. Remember to also scout for enemy wards and destroy them if possible, as denying information is almost as crucial as having it, remember however, that no gold is awarded for destroying an enemies observer ward.
