The Draconic Shadow

Your patron is a powerful, ancient dragon from the Shadowfell, a being tainted by that dark plane's insidious, corrupting energies. The dragon's motivations depend on its original form before its corruption. Because of its status, however, it is likely immensely wise and intelligent. Its goals often are driven by power-hunger and tend towards selfish desires, though the true intentions and endgames are inscrutable to you. Regardless, the sway that your patron holds on you is unshakable and instills a deep fear; their unnatural abilities and stealth leave open the possibility of a sudden appearance or dreaded command.

Fell Presence

Starting at 1st level, your patron has bestowed upon you the ability to channel its draconic might and fearful presence. As an action, you can cause each creature in a 20-foot radius originating from you to make a Wisdom saving throw against your warlock spell save DC. The creatures that fail their saving throws are all frightened by you. A creature can repeat its saving throw at the end of each of its turns, ending the effect on itself on a success. Every saving throw after the first, the DC decreases by 1.

Once you use this feature, you can't use it again until you finish a short or long rest.

Shadowy Screen

Starting at 6th level, you have gained the power to bend shadows around yourself and others, to the extent that you can lessen the effect of dark energies and can cloak your allies. As a reaction when you or a creature within 10 feet of you takes necrotic damage, the target gains resistance to necrotic damage for 1 minute, or you may take an action and give a +10 Stealth bonus to yourself and one other creature within 5 feet. The bonus ends when you enter bright light or your target travels more than 5 feet away from you.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Draconic Fortitude

Starting at 10th level, the might and agility of your dragon patron partially manifests itself in you. You gain advantage on saving throws against being frightened and become proficient in Dexterity and Constitution saving throws. In addition, once per short rest, when making a saving throw against being magically influenced (such as through the [spell]charm person[spell/]) you may add your Charisma modifier.

Corruption of the Shadowfell

Starting at 14th level, when you hit a creature with an attack, you can use this feature to infuse the creature with the dark energies of the Shadowfell and Negative Plane. Dark veins of corrupting power spiderweb across the surface of their body as the shadow seeps into them.

At the end of your next turn, the target gets disadvantage on Strength and Constitution saving throws and its speed is halved and can only attack once on its turn. This lasts for a minute. Additionally, while this is active on your turn, you can use your action to inflame the dark energy, dealing 5d10 necrotic damage to them. Due to the strain of increasing the dark energy, when you deal damage in this way, you take half of the damage that would be dealt to the target. 

Once you use this feature, you can’t use it again until you finish a long rest.
