I want my Draconic Sorcerer to be able to get two additional dialogue choices when meeting the gith patrol and their dragon:
Tav (to dragon after the arrogant gith leader's done insulting us/Laezel): "You know, my grandfather was a dragon, so I just gotta ask... Do you think I'm as hot as I think you are?". Pass an 18 persuasion check, or the dragon will instantly roast your entire group. If passed, the dragon will reply with a smirk and (if sorcerer passes an insight check) cast a lustful gaze at the Kith'rak... Laezel disapproves, and will try and smooth things over with the Kith'rak, and Laezel will have an easier time passing her own deception check because Kith'rak is distracted by being angry with the sorcerer PC.
OR
If there's a possibility for a specific dialogue option for a Red Dragon DracSorc: "Grandmommy? ". Same 18 persuasion check, but dragon will look disgusted at the thought of being related to you...unless you're githyanki.
