Actually, Sujurak might be better in that regard- strength of 14, and the domain power of the Corruption domain lets him ignore the hardness on things for one attack per day.

I dunno if we'll break free fast or if we'll actually be prisoners for a while at the beginning- but the higher level we are when we DO break out, the more spectacular it'll be as we suddenly bust out magic on the guards and such. I can totally see Sujurak casting Hold Person on one of the guards then going all Temple of Doom and tearing his heart out with a coup de grace attack, since the guard is left helpless.
