Crush

Target 1 creature within the spells range and force it to make a Strength saving throw. On a failed save, the creature takes 6d10 Force damage and is Restrained until the spell ends. As an action on subsequent turns, you can deal an additional 6d10 Force damage to the Restrained creature, after which is makes a new Strength saving throw with advantage. If the target succeeds, the spell ends.

 On a successful saving throw, the target takes half damage and the spell ends.

 Gargantuan creatures have advantage on the saving throw and are not Restrained, even on a failure.
