This was a random idea I came up with. Looking at the counter with Trifaccia, I am not too fond of it. The encounter just seems like filler with some random NPC who the party learns nothing about and are just supposed to defeat. I tend to dislike encounters like that, especially for a scene which is supposed to be as cool as they make it sound.
I was thinking, what if Triaccia is swapped out for Vencarlo, who Ileosa has masquerade as Blackjack? the idea is that, during Scarwall, Vencarlo gets captured by Ileosa's forces when she learns that he is Blackjack (via divination and her intelligence web). Ileosa then has Vencarlo masquerade as Blackjack, making it seem like Blackjack is supporting the crown. Then, instead of encountering Trifaccia, it is dominated Vencarlo instead.
Vencarlo will be buffed to be a suitable encounter, which I was thinking these stats:
Vencarlo Orisini / Blackjack CR 16

TACTICS
Before Combat: If confronted in his social identity, Vencarlo attempts to flee. If he manages to do so, then Vencarlo switches to his Blackjack identity and confronts the PC’s in a public location
During Combat: If Vencarlo goes first, he readies an action to disarm any PC that gets within his reach. If he disarms the PC, Vencarlo then focuses his attacks on the PC wearing his old Blackjack costume, making use of the time bought. If no PC wears the costume, Vencarlo instead targets the PC he disarmed, attempting to disarm if they pick their weapon up (or draw a new one), parrying as needed to avoid heavy blows. Once he manages to deal with that PC, he moves on to targeting spellcasters or healers. If any PC wields Serithtial, Vencarlo targets that PC above all others, attempting to disarm that PC and grab the weapon.
Morale: Vencarlo fights to the death while under Illeosa’s control, but if Vencarlo is freed from Illeosa’s control, he immediately surrenders to the PC’s. In the unlikely event Vencarlo manages to take Serithtial from the PC’s, he flees combat with the blade and can be found in room A52 with the false Ileosa. Serithtial can be found in room A90 in this case.

To me, this would be a more interesting and memorable encounter than one with a random Efreeti, but what do you think? would this work for a replacement encounter, or should I stick with Trifaccia?
