Origin of Legends

A legendary feat only bestow at birth to the child with the greatest potential of the era. This feat allows the user to use a subtype of magic to manipulate gravity in a specific area.

Gravity Manipulation, 1 bonus action: The user can create a field of gravity around them, giving anyone inside but them a debuff. The area begins around the user, increasing by 5 ft. every level. The user can determine the radius of this field, as well as its strength. The gravity can range from x1.1 to x5 gravity, depending on the level of the user. The multiplier limit increases by .2 every level, reaching a x5 at level 20. While in the field, all enemies have their movement reduced by 1 for every multiplier of gravity, damage reduced by 1d4 for every .5 interval multiplier, and take 1d4 more damage for every .5 interval multiplier. While in a x1.1 gravity field, enemies have 1 reduced movement, 1d4 reduced damage, and 1d4 more damage; While in a x5 gravity field, enemies have 50 reduced movement, 9d4 reduced damage, and 9d4 more damage. All living things, including allies, will be debuffed with the effects of the gravity field according to the multiplier. Any instant movement techniques like Misty Step cannot be used while debuffed. If an enemy passes a CON Saving Throw of 25, then the effects of the field will be negated; for every 1 multiplier interval, the enemies saving throw will reduced by 1d4 (x5 multiplier is a 5d4 reduction).
