Canary in a coal mine

Friday we played some pathfinder. The party picked up a GMPC to replace the missing players, and continued through the dungeon. I mean, coal mine.

( game summary )

I feel kind of bad for Alex since there's SO MANY things that can't be sneak-attacked. I remember in 3.5 there were feats and prestige classes to fix that; presumably pathfinder has something.
