Potion, very rare
A torture device of insomnia called the All-Night Mask seems to be available at the Curiosity Shop...
When you wear this mask, it removes any exhaustion you are suffering. The wearer cannot fall asleep naturally and is immune to all forms of magical sleep.
Cursed: This item is cursed. It cannot be removed by the wearer except by a Remove Curse, Dispel Evil, or Greater Restoration spell. If the mask is worn for more than three days roll on the long term madness table.
Notes: Cursed item, Healing, Cursed
