I watch a Divinity: Original Sin speed run where 2 players beat the game in
under 30 minutes.
What they do is collect all the barrels in the first town, put them in a
chest, then drop the chest on the 2nd last boss's big toe for bajillion
damage. They also collect a booby trap and use it to beat the last boss by
blowing it up as he lands on it.
GGs.
