Draxonian Suspension Field

You negate all gravitational force In a 30 foot cube centered on a point within range. Each unwilling creature must succeed on a Constitution saving throw or be affected by this spell for the duration. Likewise, When a creature enters the affected area for the first time it must succeed on a Constitution saving throw or be affected by this spell for the duration. An unwilling creature that succeeds on a Constitution saving throw is unaffected.

All objects and affected creatures that aren''t somehow anchored to the ground in the area rise vertically 20 feet, and remain suspended for the duration. A creature can make a Dexterity saving throw to grab onto a fixed object it can reach, thus avoiding this vertical movement.

Affected creatures can move only by pushing or pulling against a fixed object or surface within reach (such as a wall or a ceiling), which allows it to move as if it were climbing. Force applied to an affected creature or object causes it to move in the direction of the applied force at a rate of 5 feet per round. 

At the end of the duration, affected objects and creatures fall back down. If a creature or object manages to leave the affected area, the effect ends and it falls back down.
