The lantern creates a small area of impassible terrain while on the field. Enemies in the area when the lantern is summoned will be nudged to the nearest available space. This is not classified as crowd control (particularly, it will not interrupt channelled abilities).
The lantern's aura radius is ~150 units. This is also the range on the lantern's ability to pick up souls.
The lantern's pick-up radius is not much larger than the model-size of the lantern. However, it is possible to pick-up the lantern through small walls so long as you are within that radius.
The lantern provides vision in a small area for the entire duration.
Thresh cannot click on the lantern himself but he will be shielded if he walks near it.
The lantern cannot be targeted by Teleport.png Teleport, but it can be targeted by allied-targeted dashes.
When the lantern is thrown a golden circle is shown displaying the maximum leash range of it.
Thresh can break the leash range returning the lantern to him to instantly shield himself, if he has not been shielded by the ability already.
An ally being carried by Dark Passage will be taken to Thresh's current location, not Thresh's location when the ally grabbed the lantern.
