Gravity Knight (5e Subclass)
From D&D Wiki
Gravity knights manipulate gravity around them to encumber their enemies and to achieve feats normally too difficult to pull off in the heat of battle.
- Defying Strength
Beginning when you choose this archetype at 3rd level, you can manipulate small pockets of gravity, granting you the ability to wield 2 handed weapons as if they were one-handed. You cannot dual wield 2 weapons with the two-handed property.
- Defensive Gravity
Beginning at 3rd level, you strengthen your ability to manipulate gravity around you. Your unarmored AC is now 12 + Constitution modifier and as a bonus action you can toggle a 5ft radius around you that counts as difficult terrain for enemies.
- Gravity Change
Starting at 7th level, when you hit a creature with a melee attack, you can choose to push the creature 20 feet away from you and deal 3d8 force damage. You may use this a number of times equal to your Strength modifier, regaining all uses after a short or long rest.
- Gravity Well
Starting at 15th level, you can increase gravity in small pockets of the battlefield. As an action on your turn, you can create pockets of increased gravity centered on a number of targets you can see within 30ft equal to the attacks you can make as if you had taken the attack action. If the target fails a Constitution save (DC 8 + your proficiency modifier + Constitution), their movement becomes 0, halved if save, and they attack with disadvantage regardless of if they saved or not. Additionally, you add your Constitution modifier to your damage rolls until the beginning of your next turn when attacking that enemy.
- Event Horizon
Starting at 18th level, as an action you can create a black hole centered on you. All enemies in a 20ft radius around you must succeed a Strength saving throw equal to 8 + your proficiency modifier + Constitution modifier or be knocked prone and take 6d6 force damage. Everything is halved for a successful save, and they are not knocked prone. The area around you is now considered difficult terrain for 1 minute as the black hole dissipates. You can use this feature once per long rest.
