Sentry Ward

The Sentry Ward is an Item purchasable from the Ancient of Wonders. It produces an invisible Sentry Ward capable of spotting invisible enemies and units, but lacking in vision.

Stacks with itself in inventory.

Additional Information
Like their counterpart, the Observer Ward, Sentry Wards can be placed down anywhere to spot and assist. Unlike the Observer Ward, they have very little natural vision, but offer True Sight, which can see invisible enemies. Their detection radius is large, making them useful as long as you have vision in that area. Their primary use is for countering enemy wards, but can also be used for spotting invisible heroes by throwing one down where you expect them to show up.

Sentry Wards do not have a stock, and each stack will contain 2 wards. They also last for half the time that Observer Wards do.

Place Ward
Places a Sentry Ward to give True Sight of the surrounding area. Sentry Wards have 70 vision, 950 AoE True Sight, 200 HP, and are invisible. Sentry Wards last for three minutes.
