My analysis found that for poison needle traps, clerics and druids were almost as good as rogues, especially at low levels, and the druid will be better for the snake pits.
I admit that I made my choices without considering that later encounters are harder than earlier ones (I suspect this has something to do with lost hp, though I’m still confused by the sharp cutoff in success rates—not only to all parties beat their first encounter, for dungeons with eight or more encounters, the first two encounters are guaranteed wins, and longer dungeons have an even stronger effect.).
