Graviturgy

As an action, you can magically alter the weight of one object or creature you can see within 30 ft of you. The object or creature must be Large or smaller. The target's weight is halved or doubled for up to 1 minute or until your concentration ends (As if you were concentrating on a spell).

While the weight of a creature is halved by this effect, the creature's speed increases by 10 ft, it can jump twice as far as normal.

While the weight of a creature is doubled by this effect, the creature's speed is reduced by 10 ft and it cannot jump unless it succeeds a STR saving throw DC equal to your spell save DC.

You can push and pull creatures as your gravity magic affects all you do. Whenever you cast a spell on a creature, you can move the target 5 ft to an unoccupied space of your choice if: the target is willing to move, the spell hits it with an attack, or it fails a saving throw against the spell.

You can increase the effect of gravity on creatures and objects with fine tuned finesse. When another creature that you can see within 60 ft of you hits with a weapon attack, you can use your reaction to increase the attack's velocity, causing the attack's target to take an extra 1D10 damage of the weapon's type.

Alternatively, if a creature within 60 ft of you takes damage from a fall, you can use your reaction to increase the fall's damage by 2D10.

You can use this feature a number of times equal to your INT modifier (Minimum 1) per long rest.

Your control over gravity has increased with your studies. You can affect creatures that are Huge or larger with your Adjust Density feature. Once per long rest you can quadruple the density of the creature or quarter it.

While the target’s weight is quartered the creature’s movement speed is increased by 20 ft and their jumping distances by 20 ft.

While a target’s weight is quadrupled, the creature must make a STR saving throw DC equal to your spell saving throw DC or have their movement speed reduced to 0 ft. They repeat the save at the end of each of their turns ending the effect on a successful save.

When you use your Gravity Well feature you can move the target a distance up to five times your INT modifier (Minimum 1).

As an action, you can magically emit a powerful field of gravitational energy that tugs at other creatures for up to 1 minute or until your concentration ends (As if you were concentrating on a spell). For the duration, whenever a creature hostile to you starts its turn within 30 ft of you, it must make a STR saving throw against your spell save DC. On a failed save, it takes 2D10 Force damage, and its speed is reduced to 0 ft until the start of its next turn. On a successful save, it takes half as much damage, and every foot it moves this turn costs 2 extra feet of movement.

Once you use this feature, you can't do so again until you finish a long rest or until you expend a spell slot of 3rd level or higher (No action required).
