To clarify about the falling damage, I think Carradoc cast feather fall and timed it so that whoever wanted to jump could jump and not suffer falling damage. The spell description says Carradoc casts feather fall as a reaction and can cover up to five people within 60 feet of Carradoc when he casts. Duration 1 minute.
So, hopefully no one who jumps suffers falling damage.
Damien is staying up top for now. I didn't roll with disadvantage since I'm not sure if the shove worked or not or the order in which the actions are going to be taken.
