Xyless

She a Chaos Mage and a demon of domination trapped in the body of a mortal to help fight against Murkhal. She can be recruited by either binding her to you, or freeing her. She will then appear in one of the rooms in Whitemoon Castle. If she was bound, you can choose to keep her in your service (becomes a party member) or free her spirit from her body. If you freed her initially, you would need -15 morality for Xyless to join your party. Her quest only becomes available after completing the Honor Call quest in Act II.

She’s unique in her stats because instead of Corruption she has a Submission stat to track how under the player’s control she is. Additionally, she has two routes: either as a slave or mistress to the player, each with distinct interactions. In the second case she will be in the second floor in the Guest Room and as a slave she will be moved to the Quarters in the Right Wing later.

In combat, she has mostly debuff spells and self-buffs, that gives her a good survivability. Her stun ability is also quite useful if combined with TP related items like Helm of Confidence.
