What, no love for the bard?
A Bardic Knack Bard with Improvisation and Focusing Chant (I believe the name is), which you get at , let you achieve Max ranks -2 on any skill, ven if you don't have ranks in it, and you can get a 1/2 CL+1 boost to any skill from Focusing Chant+Improvisation, which means your Knowledge skills will effectively be 1.5*level+4 if you go pure bard, so you can dispatch things nicely.
And the best part? Both let you enhance attack rolls too, and, so you could achieve a much larger boost with Bardic Knowledge.
And those spells are unique to the bard, iirc.
Makes a nice low level skillmonkey.
(Can you see I love the bards? Melodic Casting FTW)
