Immunity is a contest function introduced in "Rescission", and evidently replaced points for the rest of Battle for Dream Island. They are usually in the form of tokens, or tickets in the rest of the object show fandom.
The concept of the immunity is basic: The first contestant(s) (first 3 in "Rescission", only one in "Gardening Hero" and "The Glistening") to finish the challenge win the immunity. The contestant can give his or her immunity to another contestant or keep it. With the immunity, any votes that the contestant receives at elimination will not count against them.
