3. What new game mechanic, appearing in this season, was introduced to the tribes on the first day of the competition?
From Quiz Survivor: Nicaragua
Answer:
Medallion of Power
The first order of business, even before actually splitting the teams, involved Jeff informing the castaways of the Medallion of Power, a new game mechanic that would allow them to give their tribe a leg up from the get-go. The Medallion, hidden in a lagoon at the introduction beach, could be grabbed by one castaway but would not be an individual reward. It was ultimately found up in a tree by Brenda, who brought it with her to the La Flor tribe when it was properly split. The Medallion, used during challenges, provided an advantage depending on the circumstances but when used, the Medallion was handed off to the other team. It was retired after four episodes.
This said, in the first episode, La Flor had the option of keeping the Medallion or trading it for a flint and fishing supplies. Whatever option they took, the other team took the remainder. (They took the fishing gear.)
