In Divinity: Original Sin, disagreements are often settled not with steel or spells, but with a game of rock, paper, scissors. Want a guard to let you pass without paying the toll? Rock, paper, scissors. Want a magical being to cough up the location of a spell you need? Rock, paper, scissors.
Here's the thing though: As goofy/enjoyable as the minigame can be, it can also get a bit arduous as the game wears on. Especially if you really just want to win the debate and get on with it. You can always save the game before the showdown and reload until you win, but that can take a while. Fortunately, there is another way.
This exploit, demonstrated by PoloMint Peeper, allows you to instantly win any match of Rock, paper, scissors. Here's what you do: Immediately as the minigame begins, hit the right bracket ] key to switch to the next party member. Then, hit the left bracket [ key to switch back. You'll automatically have won the argument.
Seems like a good way to do things, at least until the game's developers patch it out.
