What exactly counts as "natural damage reduction", for the purpose of the Student of War's deadly blow ability?
would DR gained through various class features or feats count?
What about the Stalwart feat? Or the monk's Perfect Self?
I would say that "natural damage reduction" means damage reduction gained as part of being a certain race.
That also matches the fact that knowledge checks (which the ability is tied to) would only reveal that kind of damage reduction.
Thus, damage reduction gained through feats, armor, and class abilities would not be affected.
Heh... That'd put the monk's "Perfect Self" into serious question, since it's both a class feature, and essentially a change of creature type.
So, I take it there's no answer to this in the rules?
The damage reduction due to race seems about right, but it'd be nice to have some hard rules to confirm.
Last call for input?
