I need a clarification between these two answers: 1 2
-
The first answer argues that Shield Master removes only the penalties from
attack rolls made with a shield. So for example a
character that has the Shield Master feat, has a Bonus Attack of
+6/+1 and is armed with a longsword (primary) and a light shield (secondary), his full-round attack would look like this:+4longsword/+6lightshield/-1longsword
or
+2longsword/+6heavyshield/-3longsword
with a heavy shield.

The second answer, which is corroborated by an official FAQ answer,
seems to argue instead that Shield Master removes all attack roll penalties made when attacking with a shield. So, again, a
character that has the Shield Master feat, has a Bonus Attack of
+6/+1 and is armed with a longsword (primary) and a light shield (secondary), his full-round attack would look like this:+6longsword/+6lightshield/+1longsword
or
+6longsword/+6heavyshield/+1longsword
with a heavyshield.
Which would effectively make the feat Two-Weapon Fighting
(although essential to the acquisition of Shield Master) and light shields' powerplay
(except for the fact that, unlike heavy shields, you can hold small objects with a hand equipped with a light shield) obsolete. -
A third answer (which I came up with, based on the fact that a lot of
people think that corresponding primary and secondary attacks happen at
the same time) may be that Shield Master removes all attack roll
penalties, but only when attacking with a shield. So, same
character with Shield Master, Bonus Attack of +6/+1, armed with a
longsword (primary) and a light shield (secondary), his full-round attack would look like
this (the first two attacks happen at the same time and a shield is involved so Shield Master is applied, the third one is believed to happen separately so it doesn't benefit from the feat):+6longsword/+6lightshield/-1longsword
or
+6longsword/+6heavyshield/-3longsword
with a heavy shield.
Which one of these outcomes is the correct one?
Best Answer
You only remove the penalties on shield attacks
Your understanding of the FAQ on the second answer is wrong, it says it removes the penalties when attacking with a shield, not when attacking while wielding/wearing a shield. To clarify, let me quote it again:
When you are attacking with a longsword, you are not attacking with a shield. Those are separate weapons and separate attacks, so the Two-Weapon Fighting penalties apply normally to your longsword attacks, but not your shield attacks (thanks to Shield Master).
This was clarified by Jason Bulmahn (Lead Designer back then) before that FAQ and the feat errata, which said:
This is only quoted here and there, but the actual link to that was actually broken sometime when Paizo upgraded their website in the past decade, so there are no direct links to this quote, and it cannot be found when searching their website. So, I believe this was archived or deleted and can no longer be found.
