[PF] Good picks for Unsanctioned Knowledge?

[deuxhero]

The feat (http://www.d20pfsrd.com/feats/general-feats/unsanctioned-knowledge) lets you add 1 cleric, bard, inquisitor, Oracle (which adds a total of 1 spell over Cleric...) spell to your list for each level 1-4. Seems decent enough, but what to pick.

In general, long duration buffs and utility spells are good, in combat casting is bad. I'd make an exception for stuff like confusion and dance of a hundred cuts.

Bard:

Level two should get either alter self or, preferably, heroism. Mirror Image is also an option, but it's a defensive in combat buff and as a paladin, you should have good defenses already.

Level 3 has Confusion, Charm Monster, Crushing Despair, Fear, Haste, Slow.

Level 4 has greater invisibility, hold monster, dominate person, dimension door, dance of a hundred cuts. I'd recommend dimension door, followed by dance of a hundred cuts, which is a powerful in combat buff.

Inqisitor has litany of sloth at level one.

Cleric has air walk on level 4. Divine power might also be an option, but is again an in combat buff and if you have a arcane buff caster, the haste component won't be that good for you.

Thanks (Paladin alreddy has litany of sloth at level 1 though)
