Messages

A lit field surrounds you!
You read a blessed or uncursed scroll.
You are surrounded by darkness!
You read a cursed scroll, or a scroll of any beatitude while confused.

If you are using a light source while creating darkness, one of the following messages may be appended:

Your <light source> goes out!
Your <candle>'s flame is extinguished.
Your light source is extinguished.
Suddenly, the only light left comes from Sunsword!
You are wielding Sunsword.

History

Creating a yellow or black light when confused was added in NetHack 3.6.0. Older versions of NetHack and variants will not have this behavior, and will always darken the room.

Strategy

While useful for lighting up a single room, a more efficient option is using a wand of light, spellbook of light, or a lamp, brass lantern or other light source. Therefore, this scroll is a good candidate for blanking.

UnNetHack

In UnNetHack, reading a scroll of light while confused has a different effect than reading a cursed scroll. If blessed or uncursed, it will summon 5-10 yellow lights scattered throughout the level. If the scroll is cursed, it will instead summon up to 15 black lights.
