To determine whether your target has cover from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target’s square passes through a square or border that blocks line of effect or provides cover, or through a square occupied by a creature, the target has cover (+4 to AC).
不见得是右下或左上吧,而且COVER难道不是相对的吗?
关于压制,虽然表上列出的情况和无助相同,但在擒抱条目下也明确说了这个情况不算无助.恩...可以这样理解..被压制的人物还有机会咸鱼大翻身!
