Can Trip

You create a 20ft radius cylinder within range that extends to the heavens. All creatures within the circle must succeed on a strength saving throw. If a creature fails the saving throw they can only move a maximum of of 10ft per turn or they immediately fall prone and take 1d6 bludgeoning damage, scaling for larger creatures (1d6 medium or below, 2d6 large, 4d6 huge, 8d6 gargantuan.) If a creature is airborne within the cylinder, they come crashing down to earth. All vehicles within the space lock in place as a magical golden thread holds their wheels in place. A creature must be fully outside of the cylinder for the effect to wear off.

When you cast this spell using a spell slot of 5th level or higher, the radius increases by 10ft for each slot level above 4th.
