You can blend the power of arcane and divine magic.
Prerequisites: Wis 13, Int or Cha 13, able to cast 1st-level arcane spells, able to cast 1st-level divine spells.
Benefit: You can augment the power of your divine spells with arcane energy and augment your arcane spells with divine energy.
When casting a divine spell, you may sacrifice an arcane spell slot or arcane prepared spell of that spell's level or higher as a swift action. The caster level for that divine spell increases by +1.
When casting an arcane spell, you may sacrifice a divine spell slot or prepared divine spell of the same or higher level as a swift action. Half the damage dealt by the arcane spell becomes holy (if you channel positive energy) or unholy (if you channel negative energy).
