I want to make a spell where i make my heros ulti something like metamorph. But i want it so that lets say if he was a dragon knight or mage his ulti turbs him into dragon and i ACTUALLY want him to fly in the air> because times that ive seen this happen ive seen ground units can hit the hero its like he is just floting ontop of groung but i want the hero to turn into lets say a dragon and fly and fight where the only way to attk him is to have aa or range
Make 2 units, one the main unit, the other one is the flying unit. Then, set their dependencies to each other. Give Storm Crow Form ability to each unit.
I think you should learn more about Druid of the Talon's morph ability, this ability just require object edit only, no trigger involved.
