1、。这个问题的判定有点复杂，我们慢慢看。
首先是这个，重剑faq。
劇透 - :
Bastard Sword: Is this a one-handed weapon or a two-handed weapon?
A bastard sword is a one-handed weapon (although for some rules it blurs the line between a one-handed and a two-handed weapon).
The physical properties of a bastard sword are that of a one-handed weapon. For example, its hardness, hit points, ability to be crafted out of special materials, category for using the Craft skill, effect of alchemical silver, and so on, are all that of a one-handed weapon.
For class abilities, feats, and other rule elements that vary based on or specifically depend on wielding a one-handed weapon, a two-handed weapon, or a one-handed weapon with two hands, the bastard sword counts as however many hands you are using to wield it.
For example, if you are wielding it one-handed (which normally requires the Exotic Weapon Proficiency feat), it is treated as a one-handed weapon; Power Attack only gets the one-handed bonus, you cannot use Pushing Assault or Shield of Swings (which require a two-handed weapon), and so on.
If you are wielding it with two hands (whether or not you have the Exotic Weapon Proficiency to wield it with one hand), it is treated as a two-handed weapon; Power Attack gets the increased damage bonus, you can use Pushing Assault or Shield of Swings (which require a two-handed weapon), and so on.
An unusual case of the handedness rule is an ability that allows you to treat a two-handed weapon as a one-handed weapon. For example, the titan mauler's jotungrip (which allows you to wield a two-handed weapon with one hand) allows you to wield a bastard sword in one hand even without the Exotic Weapon Proficiency, and (as the ability states) treats it as a one-handed weapon, therefore it is treated as a one-handed weapon for other effects.

根据这条faq，以此法单手用双手武，是会将它视为单手武器的来判断职业能力。faq里写明了，当判断职业能力，专长和其他跟轻单双武器挂钩的能力时，请看你用了多少手来持握和使用。
但是在判断力调和pa时，到底如何判断呢。这里涉及到另外一条faq。
根据这条faq，我们得知在单手用长枪（一个双手武器）时，是可以享受到pa1换3的。但是，注意，单手持用长枪，是享受不到力调1.5的。
其根据在于，力调1.5和pa1换3的判定方法不一样。力调1.5是需要双手持握（只要不是轻武就享受），而pa1换3需要“使用双手武器、双手持用单手武器、力调1.5的天武”。所以这里不矛盾。
但这条faq与上面的重剑faq矛盾了。按重剑faq，单手持用的长枪会在职业能力和专长方面视为单手武器，但它依然作为双手武器享受了pa1换3。这中间就出了问题了。
因此事实上这里依然是一片混沌。
且容我去翻翻帖子ok混沌解决了。这段话其实说的很清楚了，看握法认类型。能单手用，那就当做单手，能双手用，那就当做双手。长枪那个是作为特例拿出来了，那么就当做一个特例来解决。
正常情况下，既然单手拿了长武和矛，那么就视为单手武器（可以精确刺击，pa1换2，力调1）我错了，应该说，重剑这种会因为专长而改变判法的才是特例，与各种种族武器同理。只有这些特例武器才会因握法改变而改变武器类型。
长枪faq说得很清楚，是双手武器单手持握时（比如长枪），这种说法，所以在判时其实应是
一般的武器而言，即使改变握法，也不会改变武器类型。
特殊的武器（比如重剑），才会因握法改变武器类型。
2、可以，主手绑个小圆然后只用主手攻击，不会丢失小圆的ac，只会吃-1ab而已。正确的用法
