As two actions, a creature that you can touch or see within 36 meters must succeed on a Reflex saving throw or an artificial well of gravity manifests on it, pulling other objects in towards it.
While affected, all attack rolls against the creature have advantage as attacks are drawn toward it from the increased gravitational pull. In addition, attack rolls made against any other targets within 3 meters of the target have disadvantage, as the altered gravity attempts to pull the attack toward the affected creature.
An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
Any attempt to move away from the affected creature is treated as difficult terrain until more than 3 meters away unless the creature succeeds on a Reflex saving throw.
Creatures attempting to fly or levitate in the field are forcibly dragged down 6 meters per round at the end of their turn. Any creature that falls more than 3 meters in the field that strikes the ground takes double damage from the fall.
