Iron Scarf

As part of the action used to cast this spell, you must make a melee spell attack with a scarf, shawl, sash, or other string of cloth against one creature within range. On a successful hit, the scarf magically expands and becomes as hard as iron, inflicting 1d10 bludgeoning damage before returning to normal.

At Higher Levels. This spell deals an additional damage die when you reach certain levels: 5th level (2d10), 11th level (3d10) and 17th level (4d10).
