Because of your connection to the shadow realm, you have Darkvision with a range of 120 feet but are sensitive to light. You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.

You have Advantage on Wisdom and Charisma saving throws.

You have telepathy with a range of 120 feet or a number of ft equal to 10 times your level, whichever is higher. When you’re using this trait to speak telepathically to a creature, you can take a Magic action to give that creature the ability to speak telepathically with you for 1 hour or until you take another Magic action to end this effect. When you use your Mind Link trait to grant a creature the ability to speak to you telepathically, you form a mental connection with that individual. When you communicate telepathically, you may choose to send the message to all creatures you currently have a mental connection to. You may also allow those creatures to speak telepathically with one another. These effects last for as long as the Mind Link remains in effect.

If you can speak telepathically to an ally using your Mind Link trait, you can take the Help action to aid them in attacking a creature, even if you are more than 5 feet away from them.

You have Resistance to Psychic damage.

You can’t be the target of the Dream spell. In addition, when you finish a Long Rest, you gain proficiency in one skill of your choice. This proficiency lasts until you finish another Long Rest.
