Flanking/rear attack bonuses?

[Vulture]

@ShuiMienLung: What does counter-attacking have to do with flanking ? Flanking means to attack from the side (hence the name "flanking") or even the back to take advantage of the enemy's defenses being focused at the front.
Counter-attacking has nothing to do with that whatsoever.

And for that matter, neither do line attacks or teleports. I confirm the assertions made about flanking, tho. There is no such thing in KB:TL.
