The writer got mad when a goblin shoved Astarion off a cliff. It reminded me of when I had Karlach shove a goblin in lava, then a goblin ran up and shoved HER in the lava. I didn’t get mad; I took it as a learning moment: enemies can shove me back, so move away from the lava.
And this info is nowhere.
It’s in the game, I’ve never played 5e and I knew that since I’ve started playing.
