These are now magic items in my headcanon. 🤘🏼 Spelled “Piece o’ Scrolls”, and first invented by Tau Teeno the Impatient. Their somatic component is a very, very small (ie. “micro”, even) gesture with a flat palm as if in greeting/farewell, and a short but shrill vocal “eep” to finish.

The resulting effect can vary between casters, depending on the spells’ ingredients, but the most prevalent are surprise tiny napalm and long-lasting bowel disruption.
