Invincibility

Invincibility, also called immunity, is the state of being protected from elimination. It is usually earned by winning a challenge. If the teams are still banded, then the whole team wins invincibility. If the teams are merged, the invincibility normally only goes to one person.

Team invincibility
Mostly, invincibility is obtained by a person, more than one person, or a team for completing their challenge(s) first, or by doing better than the other team. This may also lead to them winning a prize for their team.
