Fient to use up AOO
I am hearing this question in the post:
* Can one use feint to cause an opponent to waste an AOO (without
their gaining the benefit of taking an AOO)?
That isn't covered by the improved feint feat, but doesn't seem to be
too much of a stretch.
As a side note, an AOO should not be considered to a discrete attack, despite
being handled through games mechanics by a discrete attack roll. The opponent
threatening the archer is assumed to be constantly trying to harm the
archer, and the AOO represents extra potential for the constant threat to
result in actual harm.
As an attack action, an archer won't be able to shoot in a round after
making the feint, since the archer only one attack action or full attack
action. However, with improved feint a move action is used, meaning
that the archer could make a single attack, but still not a full round attack.
The use to the archer is limited, but not to others nearby the opponent.
Trickier, what if the opponent chooses to not take the AOO? After all,
the AOO is at their option. If the DM has the opponent make a sense
motive, with a failure leading to a statement that "you failed your sense
motive; the archer is taking a shot; do you want to take an AOO?", then
it seems likely that the AOO will not be taken. Alternative, the DM secretly
makes the sense motive check, and, if that fails, announces "The archer is
taking a shot. Do you want to take an AOO?" If the AOO is taken then,
"Whoops. He tricked you. Your AOO is wasted."
