What counts as a Non-magical attack?

[Bane Wraith]

What counts as a nonmagical attack? What counts as a magical attack? Is an attack that overcomes magic DR automatically considered a magical attack?

Here are some examples I'd like clarified:

A) An attack by a fighter with a +1 longsword
B) A level 4 Monk's unarmed strike (w/ ki pool)
C) A natural attack by a creature w/ DR/magic
D) An attack using the spell Stone Discus

For reference you may want to consider the rules for Incorporeal creatures and Damage reduction.

There are also several effects in the game that reference nonmagical attacks, but don't necessarily cause one to become incorporeal. See a Breeze-kissed Sylph , or Subjective Reality from Occult Origins (Though the latter can be debated). This question only exists because most of the above claim to be magical "for the purpose of overcoming damage reduction".

I know that the monks can punch the ghosts, there's a FAQ that confirms that which would seem to make it function the same as the +1 weapon.

A) Magical, counts for DR/magic.
B)

Magical, counts for DR/magic:

treated as magic weapons for the purpose of overcoming damage reduction.

C)

Magical, counts for DR/magic:

Such creatures' natural weapons (but not their attacks with weapons) are treated as magic weapons for the purpose of overcoming damage reduction.

D)

Magical, counts for DR/magic at CL5:

discuses count as magic

Hmmm.... You appear to be right, Chess Pwn. At least that's one thing clarified.

And @James Risner ... Alright. I take it from that answer that any attack that counts as magical for the purpose of overcoming magic damage reduction will thus count as a magical attack.

Guess that solves the issue, if true.
