That's the thing, your characters shouldn't be revealing their names out of their own volition, because given the context it just makes them look really stupid. Especially it's someone like Tristian who should know better than to reveal his name to the creepy bird in a tomb filled with dark magic when the party already fought Soul Stealers in a similar location, especially when their leader is trying his damnedest to not give their names away.
It's the equivalent of idiot characters in horror movies where they go towards the creepy dark corner of the room. It feels really forced and punishes the players who want to act with prudence and self-preservation, that is to say, not fall for the bird's bait.
And there's nothing you can do to get around it other than meta-gaming it and using foreknowledge, which is bullshit because that is not how you roleplay. You can't even give the crow fake names and take a bluff check, which is what players would try to do.
If it were someone like Amiri, I'd get it, she's a hot headed barbarian who tends not to think that much. But literally anyone else? They'd have to be complete cretins given the circumstance.
Don't soul stealers use true names too, not given names? It seems really odd how it's that easy for them to just eat your soul if they know your parents named you Bob.
I tried Crusader's Edge. Didn't help because the game decided to have Octavia and Tristian go full retard. My character was an Alchemist. I built Octavia to be a mage, not a fighter. Tristian was the only one with crusader edge. The game also throws 6 soul stealers after losing half the party. And for some reason, everyone kept missing. You do the math.
I had to reload a save from two hours prior and replace Octavia and Reg with Harrim and Jahael and nominated those two. It went better, but it was still bullshit because I had to undo all of that progress and bring a tailored party, all because of some bullshit cinematic encounter where three party members had to have their little one on one duel with a demon (because fuck casters, am I right?) followed by a gank of 6 demons.
It probably worked better on the tabletop, but in a CRPG? Complete tedium and horseshit.
That encounter was traumatic the first time I experienced it. Linzi, the character I wanted to disappoint the least ate a crit and exploded into bloody chunks before my eyes. I found it a bit railroaded, sure, but it was an intense moment. I can't pretend I was happy, but games like this aren't supposed to be fun and fair all the time. Sometimes they have to suck and be no fun to give tension to the encounters and meaning to your triumphs. You'd feel safe if there was a way of predicting and preventing everything that could happen to you. You'd relax and then you'd get bored.
Vordakai's tomb is no joke the first time and like you I went in with no supplies and pushed forward relentlessly, eventually dying to the last man. In later playthroughs I realized that you can easily clear the thing by bringing 12 rations along and camping twice, or by just walking out the door at any time. Yeah it closes behind you in the first fight but (at least for me) it opens again after that. It's a shame actually. That tomb is fucking hard core on your first run. Like something out of an old school DnD module (I've not actually played these but I've watched youtube videos. DnD used to not fuck around). Deadly, terrifying and wholly unfair. I loved it. That bit where you enter the banquet hall and get mobbed by all the zombies is pretty awesome.
I wish I could re experience the menace and intensity of my first run in Vordakai's tomb. As a BBEG he just felt like such a genuine threat, especially as I dragged my heels doing artisan quests and had a time limit on that act before my barony fell. Discovering his story as you explored that place, the back and forth with that bastard raven, it all build him up into something that felt truly frightening. A genuine ancient evil, both iconic in that he's a lich and alien in that he's a Cyclops from a dead empire (that he killed). Until you meet him and he's a chump who you beat in two rounds of course. Flawed masterpiece is my verdict on this game.
Clearing that tomb is a piece of piss on your second attempt. There's nothing that bad in there. By that point nothing is too much of a threat to you when fully buffed, so if you've got rations to rebuff a couple times it's nothing. Ancient soul eaters have crazy AC but aren't undead. Any kind of damage works on them, including necrotic. Characters with decent AB can just kill them with weapons. I play on hard and don't minmax Valerie. I keep her in tower shield specialist, give her a +4 STR belt and a +1 flaming bastard sword, and have her at 16 base STR by this point. Her BAB, gear and weapon focus is enough that she can kill them. Buffed. Bombs kill everything and don't need to hit. Yawn. It's never as intense as the first time. "Who among you do you most fear disappointing?" Any martial. I tend to pick Valerie. "Who is the weakest?" Jubilost. Chop, chop, chop, bomb, bomb, bomb. Dead soul eaters.
