All-Night Mask

This black iron mask has wide open, bloodshot porcelain eyes being forced open.

While attuned to this mask you cannot be forced to sleep, and you gain a +10 to your passive perception at night.

Cursed: Once this item is attuned the mask melds to the wearer and they cannot take it off, and you cannot fall asleep unless you have 4 levels of exhaustion. A remove curse spell with a DC 15 + 1 for each level of exhaustion is needed to remove the mask.
