Alter Gravity

 This spell affects any size area equal to or smaller than 70 feet in any direction or diameter at the casters discretion, only one effect can be used every dawn short of a wish, even with a long rest.

• Gravity Null- affecting all objects and creatures within range effectively lose the effects of gravity. All creatures must make a DC 14 dexterity save or be considered prone.  Bludgeoning attacks have a chance(less than a 5 on a d20) to send the attacked and attacker flying 1d4x5 feet, this effect is guaranteed if the attack is incredibly forceful, such as a cannon or heavy gun. All creatures that can fly or levitate have twice their normal movement speed. Creatures stranded in the air with no way to self locomote have their movement speed reduced to 0
• Normalize Gravity- This effect creates an area of normal gravity where there was previously none. 
• Increase Gravity- This allows the caster to double the weight of any object or person in the range of the spell, having doubled their body weight and their objects weight, they will have to make a strength saving throw or take 1d4 for every foot of movement on a failed save, and rolling a 1 knocks them prone and deals 3d6 bludgeoning damage, requiring two passed saves to get up. If their new weight is less than their carrying capacity they have no penalties.
• Gravity Shift- Shifts the direction of gravity up to 90 degrees in any direction, a favorite for mages to turn any flat surface into a cliff
• Oozes, Beholders, and other creatures who are levitating or do not need legs and arms to position themselves have advantage on all dexterity checks in this spell.
