It sounds like the Deft Strike feat and the Improved Combat Expertise feat are an absolutely devastating combination.
One allows you to take a standard action to size up your opponent, then you can move. The next round, the opponent gets no advantage from armor, shields, or natural armor (if you succeed in your check.)
If your attack is some sort of devastating attack (because only a single attack benefits from this feat, with each attempt of the feat) then you can plaster the monster then and there.
Meanwhile, you can use improved combat expertise to raise your AC to untouchable levels, without having to worry about needing a high attack bonus to hit the monster.
It takes some prepreparation, I admit, and it only works for one attack, but what an attack!
As for that AC of 85, I have something to say that is meant as humor ...
In Knights of the Dinner Table, Brian said: When you're the last power in the world with nuclear weapons, you don't NEED experience points!
Well, when you have an AC that is more than twice that of a Great Wyrm Gold Dragon, you don't NEED worry about monsters.
(Well, ok, that's absolute nonsense, but still ... an AC of 85 is one heck of an AC!!!)
El Ravager comes up with his +12 Hackmaster. He swings! He ... misses. He sees your AC of 85. And he ... faints?
