Honestly, would anyone care about flight if it wasn't in Solasta?
Larian made verticality one of the main marketing points, so they need to deliver. But it seems they are content with letting you shove flying creatures to death....
Did they? Is it in one of their marketing videos?
I know Solasta did.
Its one of the first features mentioned on the steam page for example, getting a whole paragraph
The Forgotten Realms are a vast, detailed and diverse world, and there are secrets to be discovered all around you -- verticality is a vital part of exploration. Sneak, dip, shove, climb, and jump as you journey from the depths of the Underdark to the glittering rooftops of the Upper City. How you survive, and the mark you leave on the world, is up to you.
