Epic Combat Expertise...WTF?

[shilsen]

So, just so I got that, you can disarm a Combat Expertising character really easily? Disarm doesn't require you to hit their touch AC, just to avoid their AoO(which will probably miss if they're expertising) and then win the opposed attack roll, which will be really easy if they're taking a large penalty on attacks from Combat Expertise?

Absolutely. That's one of the reasons a character going full Power Attack + Combat Expertise against a smart enemy is going to be toast. The same is also true of using Sunder vs. an enemy using Combat expertise.

Because if so, that's totally going in my rat-bastardly DM tricks lineup, right along with unarmed disarm versus bows. (take their bow without an AoO and with no net penalty)

Been there, done that, got the t-shirt
