Homestead Arcana

you need to consume 6 Mask Augments in total to get this achievement since your mask starts at a 4 minute timer, each Mask Augment increases your mask timer by 2 minutes and you need to get your mask upgraded to a timer of 16 minutes to pop this achievement.. that being said, the only thing holding you back from doing this is finding all 6 Wild Bat Feathers hidden in various locations throughout the game:

• 1 in Pearl Canyon
• 2 in Petrified Forest
• 2 in Ancient Swamp
• 1 in The City

if you need pictures of where they can be found https://homesteadarcana.fandom.com/wiki/Wild_Bat_Feather is a wonderful resource

the achievement pops once you use the final Mask Augment to increase your mask timer to 16 minutes

To upgrade your mask you have to craft a potion at a cauldron which keeps increasing the length of time your mask will last for in the Miasma.

One of the items required to make this potion is a Bat Wing.

There seems to only be a finite number of Bat Wings throughout the game.

They are always found along the same route you have to take for the main story with very little additional exploration required to find them.

There seems to always be a guaranteed 1 or 2 in each area you unlock while progressing through the story ( 1 in the first areas and then 2 in the later areas)

I have not determined yet wether there are exactly enough in the game to get this achievement or wether there are more than enough meaning you could miss some and still get the achievement.
I will update when I have found extra or when some one else can advise
