Zoom has an MP cost of 8, and when cast Hero will jump directly upwards. He will go beyond the limits of the camera before landing at a random part of the stage, though if he collides with a hard platform or ceiling and then proceed to move downwards. Hero gains invincibility during the ascent, though during Zoom's startup he can be hit, cancelling the spell. During the descent, Hero will have his double jump available regardless if it is used, and can air dodge to prevent any opponents from catching his landing.
Zoom is very effective as a last resort recovery if Woosh cannot be used, though the randomness of the spell makes it inconsistent to use as a fallback recovery option. However, if Hero is within 40 units of a blast zone, there will be 2x the odds of Zoom appearing in Command Selection.
