When Adelaide comes to their fort, Ellana is up on the walls, throwing balls downward. She knows it's not doing much, both because of her poor aim and the enemy's shields, but it's at least fun.

Ellana then gets down on her knees and sets her shield in front of herself, curling behind it, ready for Adelaide to retaliate. She waits for a gap in Adelaide's throws, then lobs a snowball back without looking to see where she's aiming. It's really not that effective.
