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 randomly at one of three landing spots in the stage, though if he collides with a hard platform or ceiling he will not go all the way up. 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 where it might not even appear in the commands menu 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.
