As an action, an artificial well of gravity manifests on a creature that you can touch or see within 35 meters, pulling other objects in towards it. The creature must succeed on a Reflex saving throw or be affected by this spell.
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. At the end of each of its turns, the creature can make another Reflex saving throw. If it succeeds, the effect ends.
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.
