One-Handed Power Attack optimizing

[HeshKadesh]

Is there a way I can treat my One-handed grip as being two-handed without actually changing my grip, at least for Power Attack purposes?

It's slightly related to some jank from Path of War; Dervish Defender gets Int to AC while wielding a weapon in each hand, and not using a shield heavier than a Buckler.

Buckler's still a shield for Piercing Thunder Phalanx Stance, so I can use a Fauchard one handed, use a Buckler and Gauntlet, which means I can make 1h Fauchard strikes while maintaining the needed wielding limitations on Dervish Defender.

It does come at the comparatively minor expense of not being able to get the 3:1 ratio on Power Attacks, which is a minor annoyance, but thought I'd ask here in case anyone was aware of a way for me to count as two-handed without actually being two-handed.

Edit; if that's not possible, I'm also here if there are further tips regarding one-handed Power attack optimizing.

Thank you!

If it is wielded one-handed it is treated as a one-handed weapon for all purposes. There is exactly 1 exception: a lance while mounted.

Use the other weapon to attack?

Technically, if all attacks hit and not crit is involved the damage of a greatsword wielded by one person with the same states of another who uses two short swords should amount to about the same:

say 18 str and base power attack of -1 to hit +2 damage:

greatsword is 2d6 base + 4 str +2 50% str for two handing it +3 from power attack = 2d6+9.

two short swords are 2(1d6)+ 4 str for main hand +2 for off hand +2 power attack for main +1 for off hand = 2d6+9.

the +50% power attack for two hands add up to be the same for main and off hand. Again assuming everything hits!
