====== Paladin ======
  * gets additional Smite Evil use at each 5th level
  * Aura of Courage's ability of paladin now grants +4 saves vs fear to nearby allies
  * A paladin that takes any blackguard levels becomes a fallen paladin. As such:
    * can no longer level up as paladin
    * loses access to the smite evil feat
    * loses access to the paladin spellbook
  * Paladin and blackguard levels stack for the following:
    * //divine grace// and //dark blessing// saves bonus
    * //lay on hands// heal
    * //smite good// uses
    * //fiendish servant// level
    * caster level of blackguard spells
    * //sneak attack// damage
  * The saving throw bonus from //divine grace// is limited by paladin (and blackguard) class levels.
