Elusive Target is a Tactical Feat from the Complete Warrior. One of the abilities of the feat is "Cause Overreach" - if you provoke an AoO from movement and your attacker misses you, you get a free trip attempt against that opponent, and they don't get to try and trip you back if you fail to trip them.
Now Improved Trip gives you +4 on trip attempts, but it also states "If you trip an opponent in melee combat, you immediately get a melee attack against that opponent as if you hadn't used your attack for the trip attempt."
So, if I use the "Cause Overreach" ability and trip someone as I move past them, would I also get a free melee attack on them? I did trip them in melee combat, but I didn't actually use an attack to do it.
I'm asking for opinions on this, because it's my character and I'm biased.
It looks kind of overpowered at first glance, but really it's only likely to work once or twice against intelligent opponents before they decline to make AoO's on you, or choose a different option than a normal melee attack.
