Alla faccia della pretesa...
, se ti basta, sappi che questa è una delle domande più trite che si conoscano, e a cui si deve sempre rispondere nello stesso modo: sì, ad ogni attacco che venga effettuato nelle condizioni richieste, si applicano i dadi extra di danno bonus dell'attacco furtivo.
Lo esplicita il testo del manuale del giocatore, e lo chiariscono le FAQ e gli articoli del RoTG:
SRD:
The rogue’s attack deals extra damage any time her target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the rogue flanks her target.
Dall'RoTG:
Provided it is possible for you to make a sneak attack at all, you can make multiple sneak attacks when you use the full attack action. For example, if you have a higher initiative result at the beginning of an encounter, your foe is flat-footed and every attack you make is a sneak attack.
Dalle FAQ:
Whenever a rogue attacks an opponent that the rogue flanks,
or who is denied a Dexterity bonus to Armor Class (such as
when caught flat-footed), the rogue’s attack is a sneak attack.
It makes no difference how many attacks the rogue makes or
whether the opponent is aware of the rogue or not. (Note that
opponents who are not subject to critical hits, such as
constructs, elementals, oozes, plants, and undead, are not
subject to sneak attacks.) Note that in earlier versions of the
game only the first attack a rogue made in a round could be a
sneak attack. That is no longer the case.
