I'm having some difficulties with the interpretation of this Special Situation of Stealth.
The argument I am having with my tablemates is because this scenario:
The creature A starts her turn behind a corner with Cover and uses Stealth to approach some other, leaving Concealment, lets call it B. (A) Succeeds in her Stealth check but finishes her movement -across a flat and plain passageway illuminated with a torch- beside (B). Then (A) proceeds to use her Standard Action to attack (B).
Some of us argue (B) is Flat-footed, because (A) was on Stealth and the point Breaking the Stealth is the attack, some of us argue (A) can't be on Stealth since she did not end her turn on Cover or Concealment and thus, was observed by (B) before the attack.
