Channel Gravity

Choose a creature within range. The creature must succeed on a Constitution saving throw or suffer one of the effects, which you choose when you cast your spell:

• The creature is squeezed by gravitic forces and suffers 2d4 force damage. The damage increases by 2d4 at 5th, 11th, and 17th level. 
• The creature feels the weight of gravity pull down on it. Its speed is halved until the end of its next turn. 
• The creature becomes less effected by the forces of gravity. Until the end of its next turn, the creature's jump distance and speed is doubled.
