Fiendish Resistance. Crielle has resistance to fire damage.

Legacy of Hormenos Arkill. Crielle possesses innate strengths in magic intended to influence or control the mind of another person. She makes attack rolls for spells of this purpose with advantage. She always has the spells Friends, Charm Person, and Suggestion prepared.

Sorcery Points.
Crielle has a pool 25 of Sorcery Points to call upon. 

Awakened Mind: Crielle possesses the ability to extend her mind out into the world around her. She can detect the surface thoughts of those around her using this feature up to a range of 120 feet at will. Once per day she can intensify this ability for the duration of 10 minutes, allowing her to choose which of the minds around her she wishes to read deeper, with no limit of how many she can read within her 10 minutes of intense focus. Each person she reads in this way makes a wisdom saving throw against her spell DC to determine if they are aware of her mental touch. If they become aware of her touch on their mind, they can choose to block her using a contested wisdom saving throw. She and the person who wishes to block her must each make a wisdom saving throw, granting victory to the higher roll. After this 10 minutes has ended, Crielle suffers mental fatigue as a result of the mental strain, and loses the ability to detect the thoughts around her until she has had a long rest. The voices in the heads around her all blend into one and she can no longer tell them apart or understand the nature of the thoughts. 

Demonic Concentration. Crielle's Demonic Nature has granted her awakened mind the fortitude required to concentrate on 2 spells at one time. 

Spell Save DC = 20
