Bathane; tiefling warlock/rogue. Another one of my players’ characters in Curse of Strahd. He considers himself the most tief of lings. 

Canon Curse of Strahd NPCs he’s charmed/seduced so far:

• Stanimir- old Vistani man who lures them to Barovia in the first place
• Alenka, Mirabel andSorvia - Owners of the Blood of The Vine Tavern in Barovia village.
• Vilniusthe madman in the Amber Temple…
• A Nothic monster….in the Amber Temple
• Baba Lysaga…yes. Bathane rolled nat 20 and brought her a basket of strawberries and wine from Vallaki.

He does not discriminate. Only brings seduceration and loveration to the realms! Would he pass the vibe check?
