I kind of too much enjoy several scenes for my own comfort but here are they:
Poisoning the goblins: the way my drow was towering above them with a sly smile was priceless. Almost taken from some historical drama.
The Gnoll fight: my sorcerer accidentally was on the front line when the gnoll leader approached. I kind of enjoyed it turning him against his own... Well, what followed was even more disturbing but I guess... necessary. It was a cool surprise moment in a battle that started badly.
A close runner up was the defense of the Grove from the hordes of Minthara. I limited the use of barrels and it was very close.
