Blindness

Blindness is an inability to see. If you lack telepathy, this makes it very dangerous to move around, because you could inadvertently kill your pet or blunder into a peaceful monster. If you have telepathy, though, blindness can be quite useful as it enables you to see all monsters with brains on the level. Intrinsic telepathy is only active when you are blind.

Sources of blindness include drinking or being hit by a potion of blindness, an attack by a yellow light or raven (wearing a blindfold or towel protects against this), an adverse effect from reading a spellbook, eating rotten food, getting hit by a cream pie (Keystone Kops will throw them at you), wearing a blindfold or towel, or applying an expensive camera at yourself.

Curing blindness

There are a few ways to cure intrinsic blindness.

• You can wait for it to heal - this can take a few turns if the blindness was caused by eating rotten food or being hit by a potion of blindness, but will take many hundreds of turns if you quaffed a potion of blindness.

• Apply a unicorn horn.

• Eat a carrot.

• Cast a spell of cure blindness or extra healing.

• Drink a potion of extra healing, potion of full healing or non-cursed potion of healing.

• Praying to your god may help, but be aware that blindness is only considered a minor problem.

Extrinsic blindness, such as getting hit in the face with a cream pie, can be cured by wiping your face using the #wipe command or applying a towel, or removing whatever it is that is blinding you (a blindfold for example). Having a cursed blindfold or towel stuck to your face is considered a major problem, so if it is safe to pray, your god is likely to help you out of this predicament.
