Astarion has the demeanour of a charming and confident nobleman with a biting wit. He enjoys making sarcastic remarks and japes at other people's expense, all the while acting smug and haughty. His decades of being a vampire have left him with a lack of moral scruples compared to the more upstanding members of the party, making him come off as ruthless at best or outright sadistic at worst. However, he does have certain lines he'd prefer not to cross, specifically killing for fun
Astarion is 6'2
