Iron Scarf

As a port of the action used to cast this spell, the caster must make a melee spell attack with a scarf, shawl, sash, or belt against one creature within range. On a hit, the scarf magically expands and becomes as hard as iron, inflicting 1d10 bludgeoning damage before returning to normal once more.

Leveling: This spell inflicts an additional 1d10 damage when its caster reaches 5th level (2d10), 11th level (3d10), or 17th level (4d10).
