Immunity Idols

The Immunity Idol is a totem that symbolizes Tribal Immunity, and is awarded to the winning tribe(s) of an Immunity Challenge. Not to be confused with the Hidden Immunity Idol or the Immunity Necklace, the Immunity Idol serves as a trophy-of-sorts that grants an entire tribe exemption from Tribal Council, thus avoiding elimination.

When tribes convene at an Immunity Challenge, the winning tribe passes the Immunity Idol back to the host.

Hidden Immunity Idols
Hidden Immunity Idols Hence their name,are Hidden Idols throught the competition area. They're usually hidden in bushes (in rare occasions) or in water. If an Idol is found,the player will see the received idol in the right lower corner in the screen,displayed as a necklace. The icon can be clicked and can be given to other competitiors. You can also play an immunity idol on someone,or for yourself. Players usually decide. Near the end of the season,idols are void and cannot be played.

Fake Immunity Idols
Fake Immunity Idols were a new addition in the new update. It's description says:"It does nothing,but trick others!" revealing the fact that the contestants can give the idol away to someone. However,it is not revealed to the person who received the fake idol,that it's useless. Some eliminations actually happen by tricking people to use their fake idols. Jeff usually reacts angrily and says that the contestant won't gain immunity.

Trivia

 * In Survivor:Roblox,before updates,the immunity idol was hard to find. This was changed,so it has a bigger chance to appear as a pick-up item.
