Stealth is the mechanic that renders a unit invisible for a determined period of time. Stealth is divided into three categories: Camouflage (or Strategic stealth), Invisibility (or Tactical stealth) and Stealthed traps.
Camouflage
- Camouflaged units are revealed while being inside the line of sight (e.g. not in the fog of war, behind terrain, or blocked by nearsight) of a nearby enemy champion (with the range depending on the ability), when within the vision radius of an enemy (900 units), or from sources of True Sight.
- Stealthed units shimmer their character model for 0.6 seconds whenever they take damage.
- A unit will shimmer for every instance of damage they take, and shimmering does not make the unit targetable nor remove the stealth effect, but grants positional information to the enemy.
- When a camouflaged unit can be seen, they will be warned by an exclamation mark above them indicating they have been spotted.
Camouflage provides indicators that distinguish the state of the stealth effect.

Stealth detection
There are various ways for a champion to gain the ability to see stealth. True sight is a form of vision that directly reveals stealth. All turrets have true sight reveal as well as some champion abilities. Obscured vision will reveal stealthed units through a partially translucent outline, but does not render them targetable. When a revealed stealthed unit leaves the revealed area that unit does not experience a fade time; the unit immediately turns stealthed again. The following is a list of possible ways to detect stealthed champions:
