You were born with a simple ability many called weak, the ability to control and see through crows.
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.
You regain all spent cursed energy on a long rest.
Cursed Crows
At 1st level, you have learned how to imbue crows with cursed energy to use them as part of your technique. As an action for 1 Cursed Energy, you can imbue a raven with cursed energy if it’s restrained, grappled, or incapacitated. It then becomes one of your cursed crows, it will become charmed by you and will follow your orders. As an action, you can close your eyes giving you the blinded condition unless you have blindsight, while you see through one of your crows. While seeing through your crows, you can use your passive Perception instead of the crows. You can only see through one crow at a time and can switch between them as an action or stop as a bonus action. You start with 3 cursed crows.
Omen of Death
When you reach 3rd level, you are constantly followed by an omen of death, giving you an aura of terror. As a bonus action, you force each creature of your choice that you can see within 30 ft to make a Wisdom saving throw. On a failed save, a creature becomes frightened of you for 1 minute. A frightened creature can repeat the save at the end of its turns, ending the effect on a success.
You have advantage on attack rolls against frightened creatures.
Raven’s Eye
Starting at 6th level, your crows have been enhancing your sight. You will gain +1 to your passive perception for every crow you currently have. In addition, you can switch between crows as a bonus action and can stop seeing through them at will.
Bird Strike
Beginning 11th level, your mastery of Black Bird Manipulation has made you develop its most powerful technique. As an action for 8 Cursed Energy, you can order one of your crows to launch themselves at a creature from their flying speed range. The target must make a Dexterity saving throw. On a failure, they take 10d10 necrotic damage and have one of their limbs damaged, rolling a d6 to see the damaged limb. On a successful save, they take half as much damage and do not have a limb damaged. The crow dies afterwards.
Domain Expansion: Black Mahakala
If you reach 18th level, you gain your domain expansion. At Initiative 20, you can choose up to three targets to suffer the full effects of Bird Strike for no cost. The crows still die afterwards.
Reversal

White Bird Manipulation
With your mastery of Reverse Cursed Technique, you have learned Black Bird Manipulation’s reversal. You are now able to tame Doves for 2 CE.
As a bonus action, you can turn an amount of Crows equal to your CE modifier into Doves, spending 2 CE per Crow.
Doves operate and follow the same rules as Crows but cannot be used for Bird Strike. As part of controlling a Dove, you can spend cursed energy up to twice your CE modifier to heal a creature within 5 ft of the Dove by sacrificing the Dove. The creature regains 1d8 hit points per Cursed Energy spent.
While any allies are within 30 ft of a Dove, they have advantage on saving throws against the Frightened and Charmed conditions. If any allied creatures within range are reduced to 0 hit points or making death saves, they are instead stabilized. Additionally, a Dove can suppress an effect causing a creature within range to be Charmed or Frightened. If the Dove leaves the 30 ft radius of that creature, any suppressed effect resumes.
