In patch 7.33 for Dota 2, the Observer Ward's range and cast depended on whether the item was in the inventory alone or the same slot as the Sentry Ward. Team Spirit analyst Mark sikle Lerman drew attention to this and shared it on his personal Telegram channel.

According to sikle, if the Observer Ward is left single in the inventory, its range is 500 units, and the radius of action is 1,600 units. If the item is in the same slot as the Sentry Ward, these numbers decrease - 400 and 1,200 units, respectively.
In addition, Lerman noted that players now can ward to the upper lair of Roshan on the Dire side, which should be prohibited. At the same time, vision cannot be set inside the lower spot on the Radiant side.
