Earning this item will grant you the Vaulting Pole!
You may hold onto this item as long as you like, and upon being played privately in submissions grants the holder a 25% boost for the applicable challenge. If it is score-based, it will be increased by 25%. A time based challenge will result in 25% of your time being shaved off. The last time this can be used is when there are six players left in the game. Note that some special challenges without specific time/score elements may result in the Vaulting Pole granting either a different kind of boost or becoming unable to be played entirely.
This item can be used for any Immunity Challenge EXCEPT for the Final Immunity Challenge.
