A great technique allowing you to grab space and wield it to your command.
Cursed Energy
Starting at 1st level, you can harness your negative feelings into a usable source of energy, called cursed energy. These feelings can be harnessed into attacks or abilities. The number of cursed energy you possess is based on your class, some classes use a modifier that being charisma or wisdom (Player’s choice)
Your cursed energy DC is 8 + user cursed energy ability modifier + proficiency bonus.
Sky Shape
Beginning at 1st level, your innate technique manifests, making you able to manipulate the sky around you. As a reaction to an attack roll, you may spend 1 Cursed Energy to add +4 to your AC by distorting the sky. If that makes a ranged attack miss, you can make a cursed energy attack roll against the attacker, dealing the attack’s damage on a hit. If that makes a melee weapon attack miss, it will render the limb used in the attack useless until the beginning of the creature’s next turn.
If you have taken the dodge action, you may use this reaction on allies within your reach.
Sky Armor
Once you reach 3rd level, you have become better at manipulating the space around you. As a bonus action for 1 Cursed Energy, you may cover part of your body with a part of the sky, making it seem like the parts covered are invisible for 1 minute. While you have this armor equipped, your AC is 11 + Your Cursed Energy modifier + your proficiency bonus. You will also gain a flying speed equal to your movement speed while under the effects of Sky Armor.
Sky Shape Improvement
When you reach 6th level, your manipulation has become so refined even techniques cannot pass through you. You may now use your reaction to magic attack rolls, and you may use this reaction for 6 Cursed Energy to redirect a cone or line saving throw, returning the attack to sender if you pass the saving throw, making it not affect you or the creatures in the area.
Thin Ice Breaker
At 11th level, you have created an extension technique to your sky manipulation, literally breaking the sky as if it were ice. As an action for 8 Cursed Energy, you can force every creature in a 30 feet line to make a Dexterity saving throw. On a failure, they will take a number of d10 equal to your Cursed Energy modifier in force damage and will be knocked prone, on a success they will take half damage and will not be prone. If you are flying, the creatures have disadvantage in the saving throw.
Domain Expansion: Heaven’s Gate
Finally, at 18th level, you have learned the most powerful technique of your arsenal. Your domain is a beautiful blue sky full of clouds, with a shining sun illuminating everything. All hostile creatures inside must make a Wisdom saving throw at the beginning of their turns or be considered falling even if they have flying speed. Once the domain is over, they take the maximum amount of falling damage.
