Whether by venturing into the dark ruins of Vandia, or by coming into contact with an ancient relic from there, you have gained the ability to shape gravity in the world around you. With these new powers, you can strengthen your attacks, repel spells, and even teleport short distances. 

Level 3: Gravitational Power

You foster a source of gravitational energy within yourself. It is represented by your Gravity Energy Dice, which fuel powers you have from this subclass. The Gravity Knight Energy Dice table shows the die size and number of these dice you have when you reach certain Fighter levels.

Gravity Knight Energy Dice

Fighter Level	Die Size	Number
3	D6	4
5	D8	6
9	D8	8
11	D10	8
13	D10	10
17	D12	12

Any features in this subclass that use a Gravity Energy Die use only the dice from this subclass. Some of your powers expend the Gravity Energy Die, as specified in a power’s description, and you can’t use a power if it requires you to use a die when all your Gravity Energy Dice are expended.

You regain one of your expended Gravity Energy Dice when you finish a Short Rest, and you regain all of them when you finish a Long Rest.

Grav-Empowered Strike. You can propel your weapons with gravitational power. Once on each of your turns, immediately after you hit a target within 30 feet of yourself with an attack and deal damage to it with a weapon, you can expend one Gravity Energy Die, rolling it and dealing Force damage to the target equal to the number rolled plus your Strength modifier.

Variable Movement. You can move an additional 10 ft. on your turn. 

Center of Gravity. You can cause one creature you can see in 60 ft. to be slowed. That creature can only move at half speed until the start of your next turn.

Once you take this action, you can’t do so again until you finish a Short or Long Rest unless you expend a Gravity Energy Die (no action required) to restore your use of it.

Level 7: Proficient Magnitude

You have mastered new ways to use your gravitational abilities, detailed below.

Grav-Powered Leap. As a Bonus Action, you gain a Fly Speed equal to twice your Speed until the end of the current turn. Once you take this Bonus Action, you can’t do so again until you finish a Short or Long Rest unless you expend a Gravity Energy Die (no action required) to restore your use of it.

Heavy Hand. When you deal damage to a target with your Grav-Empowered Strike, you can force the target to make a Strength saving throw (DC 8 plus your Strength modifier and Proficiency Bonus). On a failed save, you can give the target disadvantage on their next attack roll.

Level 10: Unstoppable Body

You have Resistance to Force damage. Moreover, if you start your turn with the Grappled or Restrained condition, you can expend a Gravity Energy Die (no action required) and end every effect on yourself giving you those conditions and teleport to an unoccupied space within 10 ft.

Level 15: Shape Space

You can shield yourself and others with gravitational energy. As a Reaction, you can create a 10 ft. sphere within 30 ft. of you of negative gravitational space that cancels spell effects. Creatures, including yourself, within the sphere are unaffected by spell effects as if surrounded by an antimagic field. Area of effect spells like fireball move around the area and single target spells are consumed but have no effect on creatures inside the field.

Once you use this feature, you can’t do so again until you finish a Long Rest unless you expend 2 Gravity Energy Die (no action required) to restore your use of it.

Level 18: Gravity Domain

You summon a field of intensified gravity in the area around you. With this feature, you can cast Gravity Domain without a spell slot or components, and your spellcasting ability for it is Strength.
