Stealth

Stealth causes the unit to go invisible, causing them to not appear on the opponent's screen or minimap. Stealth does not work if the unit becomes Revealed.

Sources

Passive

These Stealth effects do not expire when broken, also the user will still become visible when broken and must wait for the Fade Time to become fully stealthed again.

Gadgets

Gadgets that provide Stealth.

Ward of Sight and Ward of Revelation are both permanently stealthed.
Scout's Electric Eyes are permanently stealthed, but is revealed if an enemy units is within 200 units of it.
Monarch's Noxious Nightcrawlers (in Ward form) are permanently stealthed. However, unlike other wards, it uses a Hero-type stealth.

Revealed

Revealed negates the effects of Stealth. All Towers Reveal enemies within its attack range, as well as the Well/Tarpit. Some items and abilities also Reveal. Wards have a different Stealth type, making it immune to some Reveal effects.

Targeted

These sources come from targeted abilities, and some of these sources come with the status effect they apply. Since abilities can't target wards, it won't reveal them.
