you want to know what the tri-force is well the tri-force is this thing that has three triangles that make an even biger triangle and when you hold it you can make a wish to bring back a friend,a 50% upgrade in your stats, or three items and it takes 6 days to find a piece of the the tri-force. ok lets say that you have two pieces and another member has the other one you and him will have a fight to see who gets all of them.
