Mind Blank... (and a side note of Can an Undead Barbarian Rage?)

[Inconsequenti-AL]

Logically (but not by the rules), bardic music should work on a mind blanked person unless the spell throttles down your emotional response, turning you into an emotional cripple.

That's what I got to wondering about... Trying to figure out how this spell was meant to work. It does seem to suggest that your emotions can't be changed by any magic or possibly any means? Which lends some possible weight to that 'emotional cripple' approach. I was wondering if that's what the designer(s) had in mind?

But, then again, I think it would make this spell break an important rule: It wouldn't be a lot of fun.
