In games as in life, you can't solve all your problems with violence. In Divinity: Original Sin 2, however, you can always teleport a boss from across the map to fight a different boss, thereby solving your problems with somebody else's violence.
I don't think I'm exaggerating when I say that Divinity: Original Sin 2 is one of the most cheese-able games in years.
Its spicy blend of systems invites all sorts of experimentation, and developer Larian is basically cool with whatever players figure out -- some rare edge cases aside.
But there are regular, everyday cheeses, like my roundabout strategy for beating the game's first big boss, and then there are those that belong atop runny, pungent pedestals in the Cheese Hall Of Fame.
Here are some great ones.
First, the boss-vs.-boss thing I mentioned earlier. YouTuber l2dusk managed to teleport the horrifying witch from Act 2 over to Grog, the bridge troll. Grog (unlike the other bridge troll, Marg) has zero chill, and decided that, boss or not, the witch had to pay the bridge toll like anybody else. When she did not, things got messy.
A handful of players have discovered that it's possible to stack noxious plants on top of each other, allowing them to slaughter tough enemies without even engaging them in combat, among other things. Above, it's MOMjvHG5Ynq9zZuunLXu's demonstration.
If noxious bulbs aren't enough, you can always just painstakingly teleport a puddle of lava around the map and then drop enemies into it. Here's Qwireca doing it to a bridge troll, the Divinity universe's reluctant lab rat.
And here's Saxapwn demonstrating one of the more popular massively OP combos in the game: the ruptured chicken. It's exactly what it sounds like. You use the "rupture tendons" ability to make an enemy bleed every time they move, and then you turn them into a chicken so that they move as far as they possibly can for multiple turns.
Finally, here's an excellent dramatic interpretation of a Divinity: Original Sin 2 barrel cheese by IronRule.
