You can also lose Stacks of Hidden if others succeed at using the Counter Stealth Ability against you.

To escape an Encounter and return to Freeplay, the Adventurers will need to let the GM know their intent to do so, then strive to end a Round with all Adventurers having 3 or more Stealth Condition Stacks each. At that point, the game will return to Freeplay and the Adventurers will need to avoid the Alert enemies, maintaining their stacks of Unseen to prevent the game entering an Encounter again.

When you Fail a Covert Skill Test in Freeplay, all creatures in True Shooting Distance(16u) gain a stack of Alert. If the creature was already at 2 stacks of Alert, you instead lose 1 Stack of Unseen. If you reach 0 stacks of Unseen, an Encounter begins.
