Stealth is a gameplay element of Armello in which a Hero becomes invisible to opponents under certain circumstances. (The player knows Stealth has been activated by their Hero becoming translucent in their view.) Additionally, while under the influence of Stealth, a Hero gains the advantage of Ambushing.
Inherently, all characters have the possibility to gain Stealth by entering forest tiles during the night cycle of a round.
Other options also exist to increase situations in which a Hero can gain Stealth: For example, selecting the Stalk amulet at loadout.
