You know, 9 int isn't that bad. Not rocking your rp, Vita is fun and cute the way she is, but she doesn't need to be over the top dumb. Rovana had a 9 wis until a resurrection... gift and that made her slightly reckless effectively. It's not that extreme to worry about it all too much.
p.s. You had Vita pick an 'equipment pack' to start off with, right? They got a gold amount noted down.
Someone should have done a persuasion roll to get some gold for escoring Esvele in advance. Ofc, best one to do that IC would have been Rovana who'd have also absconded with the gold unless anyone made sure to make her honor her deal.. only to lose it to Strahds ever hungry coffers after her little.. accident.
