Fluff that doesn't make sense

[Dhavaer]

Also, the Duskblade is an INT-caster, not a CHA-caster... that just doesn't make sense to me at ALL.

I makes perfect sense to me. The Duskblade is a trained arcane caster, like the Wizard or Assassin, instead of a natural caster like the Sorcerer or Hexblade.
