Baldur’s Gate 3 is here, and the incredibly intricate and deep Larian RPG game can be difficult to parse at the best of times, so it’s vital to be prepared. While our Baldur’s Gate 3 review is certainly worth a read, you’ll also want to be caught up on Baldur’s Gate 3 reactions too, as the feature is a little hidden, but an absolute game changer if you enable it properly.

There’s a lot going on in Larian’s newest RPG no matter which Baldur’s Gate 3 class you pick, so it can be pretty difficult to get your head around all of the game’s mechanics and features, even after plenty of hours with the game. If, like me, you’re new to D&D, you’ll want to ensure that all of your Baldur’s Gate 3 companions have this mechanic enabled as it’ll help you make the best decisions across sticky situations.

This is where the reactions feature comes into play. You might have noticed that some of your characters sometimes have the ability to react to enemy actions, be that with a specific spell or ability they’ve learned. As you only get one per round, leaving some of them to be automatic instead of letting you choose how to use them best might end up turning a fight against you, so you’ll want to have manual control over them.

Simply press Tab to open the party menu, go to the Spellbook screen, and each character in your party will have a different set of reactions. As you can see above, everyone has an opportunity attack, and enabling it will let you choose a better option in a fight if you know it’s going to present itself that round.

If you also look at Astarion’s abilities, he can sneak attack as a Rogue, so you’ll want to check out what each of your companions can do, so you know when best to seize their opportunities instead of
