Compress Gravity

You send a well of gravity to a place of your choice within 120 feet.

Any creatures caught within a 20ft radius of the spell make a constitution saving throw, on a failed save the creature takes 3d10 force damge or half that on a sucessful save.

The target's speed is reduced by half until end of the caster's next turn, regardless of success or fail on the saving throw.

(damage increases by 1d10 for every level the spell is cast above 3rd)
