Stealth

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.

Units shimmer when attacked in stealth.

Notes

• Crowd control effects do not break stealth with the exception of taunt, which forces the unit to attack.
  • Teemo's Guerrilla Warfare is a special case.
• Stealth grants ghosting inherently when not being revealed.

Camouflage

EditCamouflage is a form of stealth that renders a unit hidden from enemy vision for a long period of time. It is usually activated preemptively in order to ambush an enemy or to bypass the surveillance of hostile wards patrolling an area. It also grants ghosting.

• 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 Control Ward (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.

(Only visible to the stealthed unit)

An enemy is within 300 units outside stealth radius.

An enemy is within stealth radius.

The user is being revealed.

Invisibility

EditInvisibility is a form of stealth that renders a unit hidden from enemy vision for a short period of time. It can be utilized to sneak in on opponents as well as the ability to reposition in-combat or simply to flee from a skirmish. It also grants ghosting.

• Invisible units can only be revealed by 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.

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:

Presence detection without reveal

Unit-targeted effects cannot be cast on stealthed enemies, as they require  sight of targets. Auto-targeted effects that do not require sight will indicate whether or not they can be cast, lighting up in the HUD and becoming available to use even if the target in range is not visible. The following abilities can inform the presence of a hidden unit:

• Hecarim's Spirit of Dread can indicate the position of stealthed champions due to the particle that it generates.
• Camille's Hookshot can detect stealthed champions with the range indicator.
• Katarina's Death Lotus can detect stealthed champions due to its required auto-targeting.
• Kennen's Electrical Surge can detect stealthed champions due to the particle effect pointing in their direction.
• Morgana's Soul Shackles can detect stealthed champions due to its required auto-targeting.
• Neeko's Blooming Burst will repeat if it hits an enemy champion.
• Nocturne's Duskbringer trail will compromise the position of stealthed enemies.
• Rek'Sai's Tremor Senses will perceive the position of any moving unit regardless of stealth.
• Soraka's Starcall Rejuvenation indicates if it hits a champion.
• Swain's Vision of Empire bringing Soul Fragments indicates if it hits a champion.
• Talon's Blade's End trail will compromise the position of stealthed enemies.
• Teemo's Noxious Trap will explode but not reveal stealthed champions.
• Tryndamere's Mocking Shout can detect stealthed champions due to its required auto-targeting.
• Viktor's Chaos Storm will focus a stealthed enemy. The stealthed champion will not be revealed.
• Vladimir's Tides of Blood can detect stealthed champions due to the particle effect flying in their direction.
• Warwick's Blood Hunt trail will compromise the position of stealthed enemies.
• Fiddlesticks' Bountiful Harvest can detect stealthed champions due to its required auto-targeting.

Skill shots

Direction-targeted abilities, also known as skillshots, will still hit enemies that are not visible, but does not grant sight of them, even if the ability in question did ( True Sight exception). Note that the visible projectile will stop short of its trajectory, meaning visual and audio effects (e.g. Dr. Mundo's Infected Cleaver will make a splatter and show a small eruption of blood upon impact) indicating if a non-visible unit is hit. The following can detect hidden enemies since they function the same as if they were unseen in Brush.

• Lux's Light Binding will visibly entrap the stealthed champion without revealing the champion.
• Morgana's Dark Binding will visibly entrap the stealthed champion without revealing the champion.
• Varus' Chain of Corruption will visibly entrap the stealthed champion without revealing the champion.
• Zyra's Grasping Roots will visibly entrap the stealthed champion without revealing the champion.
• Hook-type skillshots ( Nautilus' Dredge Line, Blitzcrank's Rocket Grab, Amumu's Bandage Toss and in some circumstances, Leona's Zenith Blade and Thresh's Death Sentence) will show the effect of the hook hitting without revealing the stealthed champion hit, revealing the champion's location.
• Ezreal's Rising Spell Force will grant him a stack for each champion hit with his abilities, revealing if there are stealthed champions nearby.
