MAYBE I WILL HAVE FUN
The Doomscroll: This cursed text appears as a rotulus covered in amusing images, questionable lore, and obnoxious advertisements. After taking ownership of this item, a character who is about to take psychic damage may use their reaction to immediately and inexplicably stow any equipment they were wielding and begin deciphering the scroll. Until they take an action to pry their attention back to reality, they receive the benefits of the Mindblank spell against everything but the Doomscroll. While in this state they cannot perceive their environment directly and instead mill about aimlessly or follow the flow of a moving crowd as the Doomscroll's directs. They may intermittently laugh or voice irritation at the ever changing content the Doomscroll shows them but they are otherwise incoherent and unresponsive.
An affected character may also take an action to temporarily extend the Mindblank benefit to adjacent allies who can see the content, and doing so magically creates a gold coin on the owner's person for each additional viewer. Attempts to discard or trade the Doomscroll activate it and consumes the owner's reaction, though it can be stolen. Characters who have viewed content from the Doomscroll lose one point of Wisdom per hour, which is restored by viewing it again. As their Wisdom declines the owner is increasingly convinced of the lie that using the Doomscroll does not interrupt a Long Rest.
A Remove Curse spell allows the owner to make a DC15 Wisdom saving throw to end the Doomscrolls influence on them, at which point an Infernal contract briefly flashes on the screen notifying them that they are in breach of the Terms of Service.
