Displace Reality

You hurl a bolt of unstable entropic arcane force at a creature you can see within range. If the attack hits, the creature takes 1d6 Force damage and 1d6 Psychic damage. In addition, the creature has a 12% chance of instantly transforming into a box for 1 minute or until dispelled. Creatures with Legendary Resistances can choose to be unaffected by this feature at the cost of one use of Legendary Resistance.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the Force and Psychic damage each increase by 1d6 for each slot level above 1st. In addition, the chance of a target being transformed into a box increases by 1% for each slot level above 1st. When this spell is cast at 9th level and the target is successfully transformed into a box, the change lasts until dispelled using magic of equal or greater power, such as a Wish or a Dispel Magic spell cast at 9th level.
