Ok, so this came up. Given the following scenario:
Wizard A is your average level 5 schmuck the can cast Burning Hands.
Wizard B is also level 5 and took Spell Specialization Burning Hands.

Wizard A casts Burning Hands for 5d4 in a 15ft cone.

Can anyone point me to an FAQ that explicitly states that Wizard B does not cast his Burning Hands at 7d4 in a 15ft cone?

I am willing to give the player the ability to keep the damage slightly above the by RAW cap due to the feat investment, just wanted to know if there is an actual ruling on the matter.

Kindly keep "your two cents" to yourselves as I am mainly interested in official rules.

As per the Drawback:
"You are fanatical in your beliefs, ruled by emotion over reason. When you attack a creature that you know worships a different religion than you do, you take a –5 penalty on the attack roll and a +2 trait bonus on the damage roll with your first attack."

1)What happens if this first attack is a spell?
2)What if this spell deals damage but does not require an attack roll, such as a Fireball?
