I've just taken out Trias in my 1st ever run through and I've been under manned the whole time, I only have Annah, Falls-From-Grace, Morte, Dak'ka on my side. So I have one spot left. Given how obtuse the quests can be sometimes I've looked up quests and seen all the potential party members. Thing is I think I might have lost the ability to recruit them e.g. for Ingus have the Decanter of Water but the Quest lady (whose name I fail to recall) won't give me the key word (I can't even get the dialogue up despite doing her quest), I haven't seen the robot dude and the massive fighter (who's name I just recall glancing at in the guides) is apparently at Curst which I can't get back to (its not even fair I never saw him).

Is there any hope of getting another party member, my party is lacking a bit of firepower.

Vhailor was in the NE section of Curst Prison. And to get Nordom (robot), you'd need the Modron Cube from Curiosity Shoppe in Clerk's Ward.

All in all - you're in the hard spot at this point of the game, sorry.

Ah snap, at least I can still probably get robot boy. I will say this, as much as I am loving the setting, plot and dialogue, This game is brutally hard. Baator is fiendish in difficulty. Tomorrow I'll continue on.
