Well, I'll go for Fascinate. I'm undecided on Su vs Sp.
Fascinate (Su? Sp?): A hu hsien may fascinate a single humanoid within 30 ft. This functions as a charm person spell with a duration of 2d6 days, except that the subject becomes helpful rather than friendly. Also, the hu hsien receives a +4 racial bonus to Charisma checks if necessary to convince the subject to remain in her company. A DC X Will save negates this effect. [Either the bit about the save DC or the effective spell level.]
Looks good to me.
I'd prefer it Supernatural and Charisma-based.
