Let's assume I am playing my character in Pathfinder 2 and am attempting to stab my foe. This foe is clumsy 3 (because of a spell my friend casted earlier) and I somehow also have it flat-footed.
As far as I know being clumsy gives a status penalty to AC, as does being flat-footed, and those two penalties of the same type don't stack (so the total penalty would be -3). However pretty much anyone I played with seems to consider they stack (and thus in the former example the foe should have a total penalty of -5). Are they correct?
