The Curse of Clumsiness

You curse a creature within range, weaving strands of fate to ensure its steps falter at the worst moments. The target must succeed on a Wisdom saving throw or fall under the effects of this spell.

While cursed, the creature’s movements are plagued with misfortune:

• Whenever the creature moves more than 10 feet during its turn, it must succeed on a Dexterity saving throw or fall prone.
• If the creature attempts to Dash, it automatically trips and falls prone at the end of its movement, regardless of the saving throw result.
• The cursed creature has disadvantage on Acrobatics checks and any saving throws to avoid being knocked prone.
• As a reaction, you can force the cursed creature to repeat the Dexterity saving throw if it attempts to stand up from being prone. On a failure, it remains prone.
