Alternate Racial trait "Toothy" for ½ Orcs.

[Smitty.The.Smith]

#1 Is it an Orcish weapon?
#2 If not, why not? It is very Orcish and all Toothy Orcs are proficient.

I'm saying this because I want Ancestral Weapon Mastery to apply to the bite attack. Seems reasonable doesn't it?

[Ravingdork]

It's not mentioned in your Weapon Familiarity racial trait, so it is not in any way a legal option.

Now, if you had an extremely lenient GM willing to house rule that restriction away for you, I see no problems that are likely to arise as a result.

[James Risner]

Doesn't seem reasonable.

[Cavall]

Doesn't start with Orc or is specifically mentioned. So no.

Part two as to why not is, Well, see above.

[Claxon]

I agree with the others. It's not an orcish weapon because it doesn't have orc in the name nor is it specifically mentioned.
