40:30 "Whereas ranged attackers in particular can often gain the benefit of being hidden when they make their attack because they can make the attack from the place where they are hiding out. You know they’re in the heavy foliage, they’re up in the tree tops, they’re up on the roof of a building, and so that split second where they emerge just to make the attack they get that benefit. Now a melee attacker can similarly get the benefit if, let’s say, their target is standing right at the corner that they’re hiding behind. And so essentially if the melee attacker doesn’t have to move anywhere to make the attack. If they can make the attack from the place where they’re hiding, they get the benefit. That’s sort of to really drill into the heart of the rule, if you are hidden and you can make the attack from the place where you are hidden, whether it’s a melee attack or a ranged attack, you get the benefit but the moment that you hit or miss you’re no longer hidden."
