Specific mage hunter class ability? (solved)

[jamesb]

I know I saw this somewhere. I thought it was in 3.5, but I can't locate it now that I want to use it...

Anyone know of a class with extraordinary ability to ignore/bypass magic armor's AC boost (like mage armor)?

Maybe it was in pathfinder, 4th, 3rd party 3.5, or home brewed... :smallconfused: ...hopefully someone recognizes it if I crowdsource the problem.

You're probably thinking of the Pierce Magical Protection feat from Complete Arcane.

Yes, thank you ^.^

Prereq: Mage Slayer

Which I'd looked at but wasn't what I'd been looking for. That's why I kept thinking 'mage killer' class.
