Doom Scroll

Scroll, uncommon

This scroll appears to be a spell scroll. An identify spell reveals its true nature.

On the scroll are the apparent mystical words to a random 3rd-level spell; choose or roll a d8 to decide between bestow curse (1), fear (2), fireball (3), hypnotic pattern (4), major image (5), sending (6), stinking cloud (7), or tongues (8). Regardless of the spell, the words inscribed on the scroll are faulty: a creature that attempts to transcribe the spell or cast it by reading the scroll must immediately succeed on a DC 15 Wisdom saving throw or be incapacitated. A creature that's incapacitated in this way has a speed of 0. The creature can repeat the saving throw after 10 minutes have passed and whenever it takes damage for the duration, ending the effect on a success.

Once the creature succeeds on the saving throw, the scroll turns to ash and is destroyed.

You can't stop reading, no matter how bad it gets.
