Scroll of the Drawn Bound

Chalk-dusted paper, short, its single line of text ruled straight with a hard edge rather than written freehand.

Only wizards and clerics may read it. The reader names one kind of creature aloud and walks a line up to 300 feet long across any solid ground. For one hour no creature of that kind may cross that line in either direction, though it may reach, shoot, and strike across it. The scroll falls to a line of ash as the last word is read.
