Weight of Worlds

You impose catastrophic gravitational burden on one creature you can see within range. The target must make a Constitution saving throw. On a failed save, it takes 6d10 force damage and is overwhelmed for the duration. On a successful save, it takes half as much damage and the spell ends.

While overwhelmed, the creature’s speed is reduced to 0, it cannot take reactions, and it has disadvantage on attack rolls and Dexterity saving throws.

At the end of each of its turns, the target can repeat the saving throw. On a success, the spell ends.
