I've heard many people talk about the second crit enhancement at level 14. Word is its pretty good. But all these builds have no AC to speak of (I mean, but sorcerer has 30AC before he puts on his shield.)

So... The pure damage and high hit point barb normally has low AC and benifits greatly from arcane buffs (i.e. displacement). Are there good multi-class builds that allow you to do some of these buffs yourself (either scroll using UMD or inate casting)?

barb9 / wizard5 comes to mind. You get full level 1&2 spells and 2 level 3 spells, so you can have resists, shield, displacement, blur, haste. And you can get extend with one of the bonus meta-magics. UMD is still low though to minimal CHA, though skill points are high.

Barb13 / bard1. Saw one of these last night. Pretty neat. He said he could rez people even. Not sure how he got the UMD that high. Barb enhancements, hitpoints and damage should be pretty close to pure barb.

Barb12 / rogue 2. Use rogue levels to max out UMD. You also get evasion, though I'm not sure it helps since barbs usually don't have high dex. Even with max UMD ranks the low CHA seems rather limiting on UMD.

Thoughts?
