Whenever you are the target of a melee or ranged attack and are adjacent to an ally who also has this feat, you can initiate this feat to skillfully pull the abettor into harm's way or dodge behind the abettor as an immediate action.
You gain cover against that attack (and only that attack). If the attack misses you but would have hit you if not for the cover bonus to your armor class, the abettor becomes the target of the attack and the attacker must make a new attack roll (with all the same modifiers) against the abettor's armor class.
What kind of cover do i get from using this? Total cover? Just basic cover? Also it only states what happens if the attack would miss my due to the +4AC we get from using cover. What if that +4 is still not enough to avoid the attack? Would the attack weave its way around my meatshield and hit me?
1. Normal cover as that is all it says you get.
2. If the attack would hit your AC even with the cover bonus, you get hit normally. Don't think of it as the attack as "weaving around" your meatshield; you don't have total cover after all. It's more akin to you taking cover behind a chest high wall and the enemy landing an upper body shot on you, or like in the movies where the bad guy holds up a hostage between himself and the hero and the hero just shoots him the head or other exposed area.
3. Concerning what would happen if the attack would fail to hit your normal AC without the cover bonus, it looks like nothing at all would happen. Just a normal miss. The abettor only has the potential of taking the hit if it misses you because of the extra +4.
alright thanks for clearing that up.
i dont know if its worth it then, we'll see
