The Arena:

Throughout the pre-merge portion of this game, you will have a choice to make before every immunity challenge. You will get to choose if you'd like to visit The Arena, or if you'd like to stay and play immunity. This decision will be made privately.

The Arena can be beneficial for your game; if five or fewer people visit The Arena, you will safely leave the game for TWO rounds. The remaining players will continue the game regularly, and players will not be able to visit The Arena until those who attended return from their two-round safety and have rejoined their original tribe.

Also, there is a Hidden Immunity Idol in the Arena, only those in The Arena can claim it, you will be given clues individually that add on every time you visit The Arena.

If six or more players choose to go to The Arena, these players will lose their opportunity to visit The Arena; they will rejoin their tribe for the immunity challenge. The players who chose to attend and are on the losing tribe will lose their vote for that tribal council; if you're on the winning tribe and this event takes place, you will have won your right to vote back for the next tribal council you attend.

You make the decision, will you be brave enough to leave your tribe to get the chance at safety for two rounds, or will that decision come back to bite you?

I am aware this twist is pretty complicated, so ask me all the questions you'd like privately.
