豪臂护腕和猴爪之间规则上是否互叠？

[索拉利斯]

不叠。

 Do effects that allow you to use larger than normal
weapons, such as the Monkey Grip feat or the Powerful
Build racial trait, stack with each other?
 
 These effects do not stack with each other. If you have an
effect that allows you to use a weapon one size category larger
than you and then gain the same benefit from another source,
you are still limited to weapons one size category larger than
you.

这个FQA只说明了猴爪跟有力体型不叠，而没有说明跟豪臂护腕的关系

[aland]

effects such as ...必然不止such as後面幾個...
當然硬要說沒有'larger than you are" 也有那麼一點根據, 雖然其實one size larger 比什麼 larger最後還不是要看who you are...

[涅薇儿·德拉诺尔]

唔……最后一个问题是，豪臂是让自己视为更大一阶的生物来拿武器，而猴爪是让武器变大一阶，所以前者就描述来看，并不是跟猴爪”同样的描述“，所以这里是译文导致的歧义吗？

于是没问题了
