Steadfast Slayer + Double weapons + TWF

[Khell DarkWolf]

I can't find an answer to this question so I present you with this:

Does Steadfast Slayer work with a Double Weapon being used NORMALLY as TWF (two-weapon fighting) for each end of the weapon, given it is still a two handed weapon.

Or must the double weapon be WIELDED with both hands to be used to attack with only one end of it for steadfast slayer to work.

Steadfast Slayer:

You stand alone against creatures far larger than you.

Benefit: If you are the only character threatening an opponent and you successfully attack the opponent with a two-handed melee weapon, for each size category larger than you that opponent is, you gain a +2 bonus on your melee damage roll.

Double Weapons:

A character can fight with both ends of a double weapon as if fighting with two weapons, but he incurs all the normal attack penalties associated with two-weapon combat, just as though the character were wielding a one-handed weapon and a light weapon. The character can also choose to use a double weapon two-handed, attacking with only one end of it. A creature wielding a double weapon in one hand can’t use it as a double weapon—only one end of the weapon can be used in any given round.

It is a two handed weapon that you are wielding with two hands, yes?

This works.

Or, your GM doesn't want martials to have nice things.

Ultimately it is up to your GM, but yes it works with two handed double weapons being wielded in two hands.

Hopefully you are a small character, with a Nodachi + spear dancing style + Sap Adept/Master + Enforcer + Shatter Defenses.

The fun..

"The character can also choose to use a double weapon two-handed, attacking with only one end of it."

The way the double property is written Steadfast Slayer only works when you wield the weapon two handed, attacking with one end.

Exactly...

It's pretty much like your power attack for all Medium+ enemies.

Meanwhile you use Enforcer and the blunt end of the Nodachi in spear dancing style to deal Sap Master double damage and intimidate them. Hurtful gives you another attack once you get that far.

And Hurtful requires Power Attack, which stacks with Steadfast Slayer.

So when you two hand it with power attack on medium+ enemies, it is mighty.

Otherwise use spear dancing style to deal Sap Master double damage and intimidate them.
