When using the Ride-By attack feat, you must conduct your
charge so that you move in a straight line toward the closest
square from which it is possible to attack your chosen foe, so
long as it is a square that allows you to attack and then continue
on in the straight line of the charge.
when using..., you must conduct your charge so that........so long........
三个条件而已.其中when using和后面那一整段是并列关系, so that so long是第二层的并列关系, 同时为square的条件.
至于主句中的closest square明显不是预设概念(也没办法推论这就是个预设概念), 而已经是对ride-by的限定了(you must...so that).
断出来就是
When using the Ride-By attack feat(使用ride-by的条件), you must conduct your charge so that(和下面的so long as一起限制square的条件) you (这里隐藏了个can的含义) move in a straight line toward the closest square from which it is possible to attack your chosen foe, so long as it is a square that allows you to attack and then continue on in the straight line of the charge.
限定2和限定1又没有任何冲突.
为啥我觉得我的图和羊姐姐的图没啥区别...........
