Forbidden Secrets Beginning at 1st level, your patron has taught you to see only what matters in the world. You gain proficiency in the Arcana skill. Additionally, you learn the Detect Magic spell. It is a Warlock spell for you, but does not count against your spells known. When you cast it using this feature, it does not consume a spell slot. Instead, the world fades to black, and only things with magic properties remain in your view.

Dark Stigma Beginning at 1st level, you've learned to stoke the flames of fear in the hearts of men. As an action on your turn, you can silently reach into the mind of a creature you can see within 60 feet. It must then make a Wisdom saving throw. On a failed save, it becomes frightened of you, and must use its full action on each of its turns to move away from you. It can remake the save at the end of its turn, ending the effect on a success. You can use this feature a number of times equal to your Charisma modifier, regaining spent uses upon completion of a short or long rest.

Shadow Meld Beginning at 6th level, Sul Khatesh has taught you to mimic her form to protect yourself. As a reaction to taking damage, you can break apart into formless shadow. You can then move up to 20 feet without provoking opportunity attacks and even moving through another creature's space. If you end your turn in another creature's space, you take 10 force damage, and are shunted into the nearest unoccupied space Once you use this feature, you can't use it again until you finish a short or long rest.

Forbidden Arcana Beginning at 10th level, Sul Khatesh has gifted you a modicrum of mastery over magic, but at what cost? Choose a spell of 4th level or lower that is not a cantrip. You can cast this spell once using a Warlock spell slot. Once you do, you can't do so again until you finish a long rest. You can change your Forbidden Arcana whenever you complete a long rest.
