Random Axe said:OK, given that the ally provides a +4 AC cover bonus for the bad guy, and assuming the archer DOESN'T wait for the ally to get the hell out of the way, what happens if the archer misses his ranged attack by only a little? Does that mean the ally gets shot in the back? If the archer has the Precise Shot feat, I can just imagine the objections that would come out of that!
Nothing unless you are using the striking cover variant rules from pg 24 of the DMG.
Without that variant rule you don't strike cover on a missed shot.
The Improved Precise Shot feat is the one that allows you to ignor cover not Precise Shot.
