The deeper you delve into Baldur’s Gate 3, the more you’ll discover about the hidden surprises. I mean, it’s impossible to find every weapon or piece of gear on your first try. One such hidden item, known as the Devilfoil Mask, can be found while exploring the depths of Grymforge in Act 1. What makes this mask special over other gear is that it can be equipped by all party members for a special buff known as Infernal Legion. There’s not much explanation about this buff, but I think I have some information you can use.

So if you're curious about the Infernal Legion in Baldur's Gate 3, now is the time and place to start.

After equipping the Devilfoil Mask, you will gain the Infernal Legion effect. This can be seen in the 'Condition' section of your character's Stats menu. What it does is it increases your strength by +1 and decreases all other stats such as Intelligence, Charisma, and Wisdom by -1.

Wait a minute, there's more to it! If all party members wear the mask, each of their Strengths will increase by 3 points. On the other hand, Intelligence, Charisma, and Wisdom will decrease by 3 points. This means that the Infernal Legion Effect in Baldur's Gate 3 will be stronger if all party members wear the Devilfoil Mask.
