More like a redmage than pure caster. Can use most cloth/leather/chain types, but not plate types. Most proficient with dagger, I personally prefer sword for its superior stats, though I would reccommend raising both skills up. Can also weild club/hammers but being that the only decent of these are for whitemages, and we have a horrible proficiency in it, I am not even bothering with this.
You can sing all the debuff/damaging songs that you want while you have your songs up. Instead of thinking about the idea of twisting, or keeping up songs (they don't automatically re-pulse like they do in some other games) just think of them as buffs that last like a minute or whatever. Damaging/debuffing songs land on your target, not yourself, therefore the 2song max limit does not apply.
