Cover - Destruction of Cover
During a multi-shot attack (e.g. semi-auto or full-auto with multiple rounds hitting) that is deemed to strike Cover, if the first round’s damage exceeds the Cover AP then that AP is reduced at that point. The second round’s damage is then applied to that new Cover AP, reducing it again if the new Cover AP is exceeded. A third round’s damage would, again, be applied to the latest Cover AP…and so on.
