You cause a swirl of magic that affects the sense of balance of up to four creatures that you can see within range. Each target must succeed on a Constitution save or suffer the following effects until the spell ends:

• It has disadvantage on attack rolls, Dexterity checks and saving throws, and Wisdom (Perception) checks.
• Its speed is reduced to no more than 10 feet, and it cannot fly or climb, regardless of its abilities.
• It cannot make more than one weapon attack each turn, regardless of its abilities.
• It takes maximum damage from falls instead of rolling.
• Attacks made against it have advantage, and score a critical hit on a roll of 18–20 instead of only on a 20.
• At the end of each of the creature's turns, if it isn't prone, it must succeed on a Dexterity saving throw or it falls prone.

Each affected creature must repeat the Constitution saving throw at the end of each of its turns, ending the spell's effects on itself on a success. Undead and constructs are immune to the spell.
