Well that is true. Feels like something we too could do
if we knew how to glitch it.
It is somehow part of the game mechanic but cannot be recreated by a real player. Only by AI. This is how it feels to me.
Only once was one of my characters shoved and it made a difference.
I attacked the first front gate defense leading into the goblin-camp.
With this one high up watchtower-like position you can also reach by climbing roots.
The Goblin there just pushed

Shadowheart to her death, which made me laugh a lot.
Such a little creature, lel. How high was the chance that it works? 30%?

Anyways it was hilarious. Goblin shoved her right into the flowing river down the cliffs. Was worth the laughs.
