Vent Fan

The  is a Jump Force. It grants a multiplier of 20, but the player needs 10k Jump Force to train with it.

The  is preceded by the Trampoline and succeeded by the Gravity Propeller.

To calculate how much Jump Force you'll make in a set amount of time multiply your JF (Jump Force) multiplier by 20. Proceed to multiply your product with the number of seconds you are going to train for.

Location: From spawn, head up the left road until you come to a red building on the left. Go to the top of the building to find the Vent Fan.
