Let's see if I can guess...As thread title. In respect to Charming Gaze.
(emphasis added)SRD said:A fascinated creature is entranced by a supernatural or spell effect. The creature stands or sits quietly, taking no actions other than to pay attention to the fascinating effect, for as long as the effect lasts. It takes a -4 penalty on skill checks made as reactions, such as Listen and Spot checks. Any potential threat, such as a hostile creature approaching, allows the fascinated creature a new saving throw against the fascinating effect. Any obvious threat, such as someone drawing a weapon, casting a spell, or aiming a ranged weapon at the fascinated creature, automatically breaks the effect. A fascinated creature’s ally may shake it free of the spell as a standard action.
I would say it does IF (1) the charmed creature can identify the spell being cast, (2) the spell is harmful, and (3) the charmed creature somehow knows that it is the target of said harmful spell....so basically, the question I'm asking is, does casting a spell break Charm Person.
Any act by you or your apparent allies that threatens the charmed person breaks the spell.Oh wait, I get it the confusion. Charming Gaze, is the Su ability of a Half Vampire . Its functionally identical to Charm Person, so basically, the question I'm asking is, does casting a spell break Charm Person.
