Brush is the tall grassy terrain on a map that provides a champion (or minion/monster) a form of stealth. Upon entering the brush, the unit immediately turns invisible to enemies outside of that particular patch of brush. The unit will remain invisible until it has either left the brush or was scouted by an ability, item or an enemy unit.
- This stealth does not make your champion invisible, but hides you from units outside of that brush. You will not be revealed by stealth detections that are not placed in the brush.
Visually, this effect manifests when your champion's avatar takes on a partially transparent quality. Opposing units in different patches of brush will not be able to see each other even if they are within normal sight range.
Brush can be used in several ways to create a tactical advantage on the battlefield. First, and perhaps most apparently, one can utilize the brush to set an ambush for an enemy champion, emerging once they have passed by to cut off their escape. Brush can also be used, while fleeing, to break the line of sight and force pursuing champions to guess which direction you have gone. It can also be used to dodge passing minion waves, to hide your champion while he channels recall, or to force a ranged champion too close to melee range to continue their attack.
Wards are subject to the same limitations surrounding brush as other units. A ward placed inside a patch of brush can reveal the area inside the brush,and the surrounding of it. A placed outside of a brush will not be able to see enemies inside. Because of this, it is often preferable to place wards within a brush.
- Brush in a lane can be used to find out if the enemy has sight into a particular patch of brush. If you are in the brush, not attacking, and minions begin to attack you, then they have sight into that brush.
If an attack skill that is not a skillshot is used while in the brush, the champion using that skill will be revealed for a short time. Your champion will also be revealed when you auto-attack from within a brush. If an ally attacks from a brush, you will also be seen. Brush is subject to line of sight. For example, on Summoner's Rift, opposing units on both ends of the brush at blue buff will not be able to see each other due to a wall in between the edges of that brush.
Ways to reveal areas in the Brush
There are several ways to reveal an area in brush:
- An allied unit moves into the brush. This also includes pets such as:
- A placed in the brush will reveal within and around it for 3 minutes.
- A placed in the brush will reveal the same area as a normal sight ward, but will also reveal stealthed units.
Some champions possess abilities that directly or more often indirectly let you see into an area that is usually subject to the Fog of War or units within them, such as Brush. Most every AoE ability could reveal an opponent in it's range.
