The caster designates a target just as it begins to move on its turn, and a small invisible force wraps up the target’s legs, threatening to throw it off balance. The target must succeed on a Dexterity saving throw or fall prone. After falling prone, the target may then continue its move as normal (though it must pay the standard movement penalty to stand up).
