Woosh is the Dragon Quest Hero's Up Special Move. When it is used, Hero will create a tornado beneath his feet, allowing him to recover. It can be charged into stronger variants (Swoosh and Kaswoosh, in order from the weakest). The level of height Hero gains can be controlled very accurately by holding the button a different amount of time despite the fact that the move only has three charging stages. Hero is left helpless after using this move.
Woosh is the uncharged version of Hero's Up Special. Upon pressing the button, Hero creates a single tornado under his feet that doesn't send him very far up and maintains the same height while it lasts. The tornado deals little damage.
Swoosh is the medium-charged version of Hero's Up Special. Upon pressing the button, Hero creates two tornadoes under his feet that intertwine with each other while they last and send him quite far. As opposed to this move's other variations, the tornadoes will descend slightly while they last, making it move effective to hit enemies that are under you and trying to hit you with an anti-air move. The damage dealt is significant but the knockback is unreliable for KOs as you never really know which direction it's send the enemy and isn't really powerful altogether.
Kaswoosh is the fully charged version of Hero's Up Special. When the charge time ends, Hero creates two tornadoes that intertwine with each other quite fast and deal large amounts of damage, but the knockback is unreliable as it can send the enemy either right or left and insufficient for KOs. The amount of height gained is vary large, slightly lower than that gained with Power of Flight allowing for recoveries where other characters would be done for. It costs less MP that Hero's other fully charged Special moves, meaning using this won't hinder you too much in the MP aspect.
