All Knowledges as class skill?

[NineThePuma]

What's a quick way to do it that doesn't require a dip and Able Learner?

EDIT: Nevermind, the trick I wanted is moot, as I can do it with the class I'm already taking.

Education Eberron feat. There might be more...

A dip from whence?

The Eberron 1st-level only feat Education feat and Well Read from Dragon #315 make all Knowledges class skills.

Initiate of Boccob from Dragon #342 lets you do all Knowledge checks untrained.

There's a few that give you a +1 bonus to all Knowledge checks, but I don't think that's what you're after.

I don't know of any non-feat methods.

I wanted to build a diplomancer that wasn't a bard or aristocrat, and I actually took a look at the class I was already taking and realized I'd screwed up. I already have the knowledge skill I want without wasting a feat.

Not that it matters now, but Factotum has all skills as class skills and is versatile enough that as long as you're not trying to be a primary caster, you can probably trick it out to do what you want (skillmonkey/archer/assassin/crafter/diplomancer).

This thread (http://www.giantitp.com/forums/showthread.php?t=176427) has some good tips on using Knowledge to it's full advantage. From there, here's my list of classes that get all Knowledge skills:

Adept
Archivist
Aristocrat
Bard
Cleric (Knowledge domain)
Dragonfire Adept
Duskblade
