Weapon Focus(Feat) and Heirloom Weapon(trait)

[Marcus Steelfeather]

Let's supose I make a character that is not proficient with Naginatas, but I have the Heirloom weapon trait that gives me the "Ascending Dragon" a naginata sword that is in my family for generations:

1. Can I take weapon focus with the weapon , like Weapon Focus(Naginata)?

2. If not, can I take Weapon Focus(Ascending Dragon) for that specific weapon?

[James Risner]

Links to options?

If I remember Heirloom correctly it grants proficiency with a simple or martial weapon?
Then weapon focus requires proficiency with a weapon, that you don't have completely but you do have on that one?

Technically it wouldn't be legal but you GM would be fine allowing it.

Heirloom Weapon

Prerequisites

Some feats have prerequisites. Your character must have the indicated ability score, class feature, feat, skill, base attack bonus, or other quality designated in order to select or use that feat. A character can gain a feat at the same level at which he gains the prerequisite.

A character can't use a feat if he loses a prerequisite, but he does not lose the feat itself. If, at a later time, he regains the lost prerequisite, he immediately regains full use of the feat that prerequisite enables.

So Heirloom weapon does give you proficiency in your specific weapon.

If you weapon is a Naginata, you meet the prerequisite, but only when using that weapon. So you can take Weapon Focus(Naginata), but it only applies when wielding your specific weapon. With any other naginata, you do not have proficiency, and thus would lose access to Weapon Focus, and any other feat that has weapon focus as a prerequisite.

I think Imbicatus has it right, but I also know you will have table variance.

Always relevant to Heirloom Weapon: Opalescent White Pyramid Ioun Stone.

As an aside, naginatas are not swords.

It's kind of like a sword mounted on a stick. Kind of.

You can take options if you have a limited version of the prerequisite, but the limitation carries forward.

The problem with "naginata sword" is that it's redundant. The second character of "長刀" is "sword". Same problem with "kanji character" (漢字 Chinese Character) and "katana sword" (刀)

[Marcus Steelfeather]

Sorry, it's not a naginata, it's a Nodachi. I always swap the names of these two.

Also redundant: 野太刀

Since almost everyone seems to agree on that you can take WF on the specific heirloom weapon "Ascending Dragon" .
If you manage to acquire temporal proficiency with all the rest of nodachis (for instance through the champion spirit of the medium class or the spell Bestow Weapon Proficiency), does the feat apply to all nodachis while you have the proficiency?
