Invisible

Not to be confused with Visibility.

“	Prevents being targeted by enemy attacks if the unit is not blocking.	”
	—In-game tip

Invisible, or Invisibility, is a buff in Arknights.

Effect

Invisible units are indicated by having their body obscured in a dark cloud of smoke, with the exception to Magallan's Soaring Dragons who are obscured by digital disruptions instead. In this state, the unit cannot be targeted by ranged attacks and are unaffected by splash damage (e.g. Splash Caster and Artilleryman Sniper attacks, Senior Casters, and Bombtails) and offensive skills/abilities, except when they are blocking or being blocked. This means that invisible enemies can be major threat as they could cause serious damage if not dealt with quickly.

Do note that invisible units can still be damaged by the following:

Heated Paths
Lava Cracks and Gas Sprays for friendlies
Hoshiguma's Thorns, Nian's Copper Seal, and Bubble's "Beaten Up" for enemies

Certain methods can "reveal" invisible units, negating it:

Invisible enemies can be revealed with the following:
- Detectors (only available in certain operations)
- SilverAsh's Eagle Eyes talent
- Tsukinogi's Without a Trace skill
- Elysium's Monitor skill
- Buggy Cams deployed by Scene, which reveals invisible enemies around them
Technical Scouts reveal nearby invisible friendly units.
Nova Knightclub Trainees/Elites and Candle Knight Viviana will lose their invisibility while casting their Glimmering Touch special attack.

Trivia

Before the term "Invisible" was introduced, all enemies with this buff contained "Cannot be attacked unless blocked" in their tips.
While sharing a similar visual effect of a cloud of smoke, albeit lighter, Jessica's Smokescreen does not make her invisible, only giving her Physical/Arts dodge.
