This game needs a line of brews that allow you to hold your breath longer. It could go along the same lines as the food except instead of extra minutes, you get extra seconds. For example, a tier 1 waterbreathing brew gives you 10 seconds extra and a tier 5 gives you 50 seconds extra. I’m sure this isn’t the first request of this sort and it would be very well received by the community if it were added to the game.
Not to mention it would produce some pretty cool underwater builds.
