Do server-specific melee feats apply to the offhand?

[Rudolph]

For example:

Would a dual-wielding kama monk with Northlander Hewing get the latter's damage boni (full weapon dmg +STR modifier as dmg) on both kamas?

If so, I have a somwhat technical follow-up question that is relevant to the build plan I have in mind: if, at 26+ BAB, I want the off-hand to have three attacks left with Northlander Hewing on, would I need to have Perfect Two-Weapon Fighting? Or would GTWF be enough? In other words, does the NH attack number penalty remove off-hand attacks that are anyway removed by PTWF?

[Valefort]

NH works by removing the last half of the attacks in your attack schedule, whatever it may be. For someone with GTWF and 26 BAB the last 4 attacks ont he attack schedule will be removed ie all the off hand attacks and the last main hand attack.

Thanks Valefort. This seems new.

So nine attacks would lose 4, i.e. the number of attacks lost is rounded down? Good to know.

On a related note, do Flurry attacks get included in this calculation (including the inoffical attack)? Does Haste? They didn't use to, so I presume not, but then does that mean with Greater Flurry and Haste on you would basically have the following?

This
Main-Hand: (45/45 / 45/40/35)/(30/25/20 / 47)/(47
Off-Hand: 45/40/35)

is northlandered into this:
Main-Hand: (45/45 / 45)/(40/35/30)/(25 / 47/47)

[Valefort]

They're counted as well now, included the bugged flurry attack.

[Rudolph]

Aaargh. That gimps my idiosyncratic epic Monk/Barbarian build!

[Rudolph]

Does this new way of counting every attack also apply to the other attack reducing combat feats?

[Valefort]

Yes, unless I missed one by mistake.

[Rudolph]

Raaah. What a change. One last question: Is Shield Bash counted in, too? Hopefully not (since it's too weak to justify losing any proper attack for)...

[Valefort]

It's not.

Yes, unless I missed one by mistake.

Does it work like this for Sembian Fencing?

I don't have PTWF or any TWF feats to test with, but just holding an offhand weapon with 27BAB, so a total of 6 attacks mainhand, and 1 offhand: it seems to only count the mainhand attacks for bonus purposes. And the offhand attacks just seem to disappear without being counted for anything.

Is that right?

Thanks!

Yes.

Is that right?

No, I didn't consider this case or using two weapons without having TWF feats.
