I think Resistomentum should also be an aoe spell for other's because sometimes other's might not have in there hotbar lines or don't know where to find the spell in time while they are in the air. As you can see in harry potter of year 3 in quidditch that he's falling down and while Dumbledore is using Resistomentum spell to save his life of not only it can be used on yourself but it should be also an aoe where a spot of where you cast your spell at while the person is landing on the ground that they should take no damage and maybe it should be like the same function like epifio does of being heal other's while you crouch down and heal. Maybe for the buttons the aoe should be spread out like how immoblio does but when someone reaches to the ground they should take no fall damage of a group of people and should be a cooldown when you used the aoe button or using it on yourself if you don't have a group of people with you. And for the key button of the aoe it should be the same function as epifio left button for the aoe anywhere on the ground and when you crouch and use this spell it should go off when you land from the air.
